This typeof cloud is very extensive, both horizontally (about 10 km indiameter) and vertically (up to 15 km). Its highly characteristicshape is often compared with the profile of an anvil of whichit displays the upper and lower horizontal planes. The existenceof extreme temperature gradients in a cumulonimbus(the temperature can drop to -65 °C at the top) generatesvery rapid ascending air currents, and results in the electricalenergisation of the water particles.In a typical storm cloud, the upper part, consisting of icecrystals, is normally positively charged, whilst the lower part, consisting of water droplets, is negatively charged. Consequently, the lower part of the cloud causes the developmentof electrically opposite charges (i.e. positive over the part ofthe ground nearby).Thus the cumulonimbus formation constitutes a sort of hugeplate /ground capacitor whose median distance can oftenreach 1 to 2 km. The atmospheric electrical field on theground, about 600 V/m in fine weather is reversed and canreach an absolute value of 15 to 20 kV/m when a grounddischarge is imminent (the lightning stroke).Before and during the appearance of the lightning stroke, discharges can be seen both within the cloud and betweenclouds.LightningAccording to the direction in which the electrical dischargedevelops (downward or upward), and the polarity of thecharges it develops (negative or positive), four classes ofcloud-to-ground lightning stroke can be distinguished. Inpractice, lightning strokes of the descending and negativetype are by far the most frequent: it is estimated that on plainsand in our temperate zones, they account for 96 % of allcloud / ground discharges.Mechanism of a lightning strokeIt is impossible to discern the individual phases of the lightningstroke by simple visual observation. This can only bedone with high-speed cameras. Most lightning bolts exhibitthe following phenomena: a leader leaves a point in thecloud and travels about 50 m at a very high speed of around50 000 km/s. A second leader then leaves the same point, follows the previous path at comparable speed, goes beyondthe final point of the first leader by an approximately identicaldistance, then disappears in turn.The process is repeated until the tip of the last leader reachesa point a few dozen metres, or even just a few metres aboveground level.The ascending jets then converge, producing a return strokefrom the ground towards the cloud (the upward streamer) duringwhich the electric current circulates: The convergence ofthese two phenomena produces the main discharge, whichmay be followed by a series of secondary discharges, passingunbroken along the channel ionised by the main discharge.In an average negative lightning stroke, the maximum currentis around 35 000 A.----------- - - -+++ ++++ + ++++++++++ + + + + + + + + + + + + + + + + + + +ABB OPR lightning protection systems | 3Lightning protection technologiesThe effects of lightningThe effects of lightning are those of a high-strength impulsecurrent that propagates initially in a gaseous environment (theatmosphere), and then in a solid, more or less conductivemedium (the ground):– visual effects (flash): caused by the Townsend avalanchemechanism– acoustic effects: caused by the propagation of a shockwave (rise in pressure) originating in the discharge path;this effect is perceptible up to a range of around 10 km– thermal effect: heat generated by the Joule effect in theionised channel– electrodynamic effects: these are the mechanical forces appliedto the conductors placed in a magnetic field createdby the high voltage circulation. They may result in deformations– electrochemical effects: these relatively minor effects areconveyed in the form of electrolytic decomposition throughthe application of Faraday's law– induction effects: in a variable electroma-gnetic field, everyconductor harnesses induced current– effects on a living being (human or animal): the passage ofa transient current of a certain r.m.s value is sufficient toincur risks of electrocution by heart attack or respiratoryfailure, together with the risk of burns.Lightning causes two major types of accidents:– accidents caused by a direct stroke when the lightningstrikes a building or a specific zone. This can cause considerabledamage, usually by fire. Protection against thisdanger is provided by lightning air terminal systems– accidents caused indirectly, as when the lightning strikes orcauses power surges in power cables or transmission links.Hence the need to protect with SPD the equipment at riskagainst the surge voltage and indirect currents generated.Protection against direct lightning strokeTo protect a structure against lightning strokes, a preferredimpact point is selected to protect the surrounding structureand conduct the flow of the electric current towards theground, with minimal impedance on the path followed bythe lightning. Four types of protection systems meet theserequirements.Protection systems StandardsEarly streamer emission air terminal - France: NF C 17-102 (September 2011 edition)- Argentina: IRAM 2426- Spain: UNE 21186- Macedonia: MKS N.B4 810- Portugal: NP 4426- Romania: I-20- Slovakia: STN 34 1391- Serbia: JUS N.B4.810Single rods air terminals IEC 62 305-3Meshed cages IEC 62 305-3Stretched wires IEC 62 305-34 | ABB OPR lightning protection systemsLightning protection system with early streamer emissionair terminal (ESEAT)These state-of-the-art technologies have been designed onthe basis of a series of patents registered jointly by HELITAand the French National Scientific Research Centre (CNRS).The OPR is equipped with an electronic device which is highpulse voltage of known and controlled frequency and amplitudeenabling the early formation of the upward leader which isthen continuously propagated towards the downward leader.This anticipation in the upward leader formation is essentialwith regard to the last scientific knowledge on the lightningattachment that acknowledge the fact that this one resultsfrom an upward leader competition. Today the upward leadercompetition is internationally recognized thanks to high speedcameras pictures of this phenomenon of attachment and to itsdigital simulation.The OPR draws its energy from the ambient electrical fieldduring the storm. After capturing the lightning stroke, the OPRdirects it towards the down conductors to the ground where itis dissipated.Triggering time of an ESEAT1 2Lightning protection technologiesABB OPR lightning protection systems | 5The early streamer emission (ESE) conceptDuring a storm, when the propagation field conditions arefavourable, the OPR first generates an upward leader. Thisleader from the OPR tip propagates towards the downwardleader from the cloud at an average speed of 1 m/µs.The triggering time ∆T (µs) is defined as the mean gain atthe sparkover instant (continuous propagation of the upwardleader) obtained with an ESE air terminal compared with asingle rod air terminal exposed to the same conditions. ∆T ismeasured in the high-voltage laboratory, all tests are definedin appendix C of the French standard NF C 17-102.The triggering time instance gain ∆T is associated with atriggering time distance gain ∆L.∆L = v. ∆T, where:– ∆L (m): gain in lead distance or sparkover distance– v (m/µs): average speed of the downward tracer (1 m/µs).– ∆T (µs): gain in sparkover time of the upward leadermeasured in laboratory conditions.OPR air terminals are especially effective for the protectionof classified industrial sites, administrative or public buildings, historical monuments and open-air sites such as sportsgrounds.Lightning protection technologies6 | ABB OPR lightning protection systemsLightning protection technologiesLightning protection system with meshed cagesThis principle consists of dividing up and more easily dissipating thelightning current by a network of conductors and earths.A meshed cage installation has multiple down conductors andconsequently provides very effective protection for buildingsthat house equipment sensitive to electromagnetic disturbance.This is because the lightning current is divided among the downconductors and the low current circulating in the mesh creates verylittle disturbance by induction.A meshed cage installation is made up of:– devices to capture the atmospheric discharges consisting ofstrike points– roof conductors– down conductors– protection measures against injuries to leaving being due totouch and step voltages (e.g. warning notice)– an equipotential bonding between each earth and the generalearthing circuit of the structure; this one must be disconnectable.Installation conditionsLightning Protection System with an ESEAT is made of:– an Early Streamer Emission Air Terminal and its extension mast– two down conductors, or in case of several ESEAT oneconductor per ESEAT– a connecting link or test joint for each down conductor toenabling the earth resistance to be verified– a protecting flat to protect the down conductor for the last twometers above ground level– an earth designed to dissipate the lightning currents at thebottom of each down conductor– an equipotential bonding between each earth and the generalearthing circuit of the structure; this one must be disconnectable– protection measures against injuries to leaving being due totouch and step voltages (e.g. warning notice).Lightning protection system with single rod air terminalBy protruding upwards from the building, they are likely to triggerthe release of ascending streamers and thus be selected asimpact points by lightning strokes occurring within the vicinity of thestructure.This type of protection is especially recommended for radio stationsand antenna masts when the area requiring protection is relativelysmall.A single rod air terminal protection is made up of:– a rod lightning air terminal and its extension mast– two down conductors– a connection link or test joint on each down conductor to checkthe conductor earth resistance– a protecting flat to protect the down conductor for the last twometers above ground level– an equipotential bonding between each earth and the generalearthing circuit of the structure; this one must be disconnectable– protection measures against injuries to leaving being due totouch and step voltages (eg warning notice).ABB OPR lightning protection systems | 7Lightning protection technologiesStretched wiresThis system is composed of one or several conductor wiresstretched above the protected installation. The protection area isdetermined by applying the electro-geometrical model.The conductors must be earthed at each end.A stretched wire installation requires a thorough preliminary studyto consider issues such as mechanical strength, the type ofinstallation, and the insulation distances.This technology is used to protect ammunition depots and as ageneral rule in circumstances where the site cannot be protectedby using a building structure to support the conductors thatconvey the lightning currents to the earth.Protection against indirect lightning stroke effectsWhen lightning strikes cables and transmission lines (H.F. coaxialcables, telecommunication lines, power cables), a voltage surgeis propagated and may reach equipment in the surrounding. Thisvoltage surge can also be generated by induction due to theelectromagnetic radiation of the lightning flash.This can have many consequences: premature componentageing, destruction of printed circuit boards or component plating, equipment failure, data loss, programs hanging, line damage, etc. This is why you need to use Surge Protective Devices toprotect equipment liable to be affected by lightning strikes.The use of Surge Protective Devices is highly recommendedwhen the building is fitted with an external lightning protection. Atype 1 SPD is highly recommended or even mandatory in somecountries. A good protection is made in step with one type 1 fittedin the MDB when the SDB are fitted with type 2 SPDs.Early Streamer EmissionAir TerminalMDBSDB - SubDistribution BoardSDBTelephone inputMainpower inputMDB - MainDistribution BoardTelecomboardEquipotential bonding of metal partsDuring a lightning stroke or even as a result of indirect effects, equipotential bonding defects can, by differences in potential, generate sparkover causing risk for human being or fire into thestructure.This is why it is an essential part of effective lightning protection toensure that a site's equipotential bonding is effective and in goodcondition.The necessity of an electrical insulation between the air terminationor the down-conductor and the structural metal parts, themetal installations and the internal systems can be achieved byproviding a separation distance "s" between the parts. 8 | ABB OPR lightning protection systemsLightning protection risk analysisRisk analysisAll lightning protection standards recommend a preliminarylightning risk analysis in three parts:– lightning risk evaluation– protection level selection– protection device definition.We have developed a software based on the calculations ofthe IEC 62305-2 or NF C 17-102 (appendix A) in order to giveyou an easy and accurate solution regarding the risk analysisof any installation you wish to protect.Lightning flash density map (flashes per km² per year)Protection device definitionIt is advisable to take into account the technical and architecturalconstraints when configuring the different components ofthe protection device.To facilitate your preliminary studies, we will provide a questionnairein which the minimum required information can beentered, and a calculation software package. 2 < Ng < 8 8 < Ng < 18ABB OPR lightning protection systems | 9Lightning protection technical studyOPR Designer softwareABB is happy to provide you with a complete new software in the field of lightningprotection.With a very simple approach you can create your technical study in one click!You can either draw, import file (AutoCAD, pictures…)and from that point get a complete bill of material(air terminals, down conductors, fixing accessoriesand earthing system), the positioning of the lightningprotection system on the structure.The solution is given in a complete pdf file that includes :– protected areas– lightning air terminals positioning– complete bill of material– detailed bill of material per building– catalogue pages for each component– test certificatesThis software is so far available in English, French, Spanish, Russian and Lithuanian version.You may download OPR designer at the following address :http://www.web-emedia.com/opr/10 | ABB OPR lightning protection systemsProcedure for measuring the Early Streamer Emission of an ESEair terminal according to standard NF C 17-102 appendix CThis test procedure consists in evaluating the triggering timeof an Early Streamer Emission (ESEAT) compared with thereference Single Rod Air Terminal (SRAT) in high voltage laboratoryconditions. 50 shocks are applied to the single rod air terminalin the first configuration, then to the early streamer emission airterminal in a second configuration.Simulation of natural conditionsNatural conditions can be simulated in a laboratory by superimposinga permanent field and an impulse field associated with a plate /ground platform area (H). The tested lightning air terminal is placedon the ground, beneath the centre of this platform. In the experiment, the height H = 6 m, and the lightning air terminal heighth = 1.5 m.Electrical conditionsThe permanent field caused by the charge distribution in thecloud is represented by a negative DC voltage of -20 to -25 kV/m(simulating a negative field of around -20 to -25 kV/m) applied tothe upper plate. The impulse field caused by the approach of thedownload leader is simulated with a negative polarity wave appliedto the platform. The rise time of the wave Tm is 650 µs. The wavegradient, at the significant points is around 109 V/m/s.Geometrical conditionsThe volume used for the experiment must be large enough to allowthe ascending discharge to develop freely:– distance d between upper platform and tip ≥ 1 m– upper plate diameter ≥ distance from upper plate to ground.The lightning air terminal are tested in sequence in strictly identicalgeometrical conditions same height, same location, same distancebetween tip and upper platform.ESE air terminals triggering time calculationGeneral conditions– number of shocks: around 50 per configuration (sufficient for anaccurate analysis of the leader /Leader transition)– interval between shocks: the same for each configuration equalto 2 min.Recording– triggering time (TB): obtained directly by reading the data fromthe diagnostic equipment. This data is not characteristic, butit does enable a simple reading to establish whether or not ashock can yield a valid result– light emitted by the leader at the lightning air terminal tip (photomultipliers):this data provides a very accurate detection of theleader continuous propagation instant– pre-discharge current (coaxial shunt): the resulting curves confirmthe previous diagnostic data– space-time development of the discharge (image converter): theimage converter pictures provide a further means of analysingthe results.SRATLABORATORY EARTHdhHPLATEdhHESEATLABORATORY EARTHPLATEIREQ Laboratory (Canada - 2000)Other recordings and measurements– short-circuit current (coaxial shunt)– time/voltage characteristics for several shocks– rod to plate distance before and after each configuration– climatic parameters must be maintain for the 2 configurations :- pressure ±2 %- temperature ±10 %- relative humidity ±20 %.Triggering picture of a SRAT witha rotative high speed camera.Triggering picture of an ESEAT witha rotative high speed camera.ABB OPR lightning protection systems | 11Procedure for measuring the Early Streamer Emission of an ESEair terminal according to standard NF C 17-102 appendix CProcedure for measuring the Early Streamer Emission of an ESEair terminal according to standard NF C 17-102 appendix CT TESEATTSRAT t(µs)EESEATESRATEM expreference wavemeasuring waveDetermination of the early streamer emission of the ESEATThe triggering time instants, or continuous propagationinstants of the upward leader are obtained by analysing thediagnostic data described above.

For this purpose, weare using high speed cameras, lightning current recorders aswell as field and light recorders.Another in situ test runs at the Taoulet station 2300 m to verifythat theoretical values announced are also validated in realconditions.A constant partnership with scientists permits to follow thesein situs sites and lead to fundamental research on lighting. Asan application example, a software that determines the weakpoints of a structure has been developed.Natural lightning experimental site– Located in the Hautes Pyrénées department of France– Keraunic level: 30 days of storms per annum.Experimental artificial lightning triggering sitesBecause lightning is a randomly occurring naturalphenomenon, artificial triggering techniques have beendeveloped to speed up the research process.When lightning conditions are prevalent the triggeringtechnique consists in sending a rocket with a trailing wire inthe direction of the storm clouds to cause a lightning strike atthe experimental site.The wire may comprise an insulating section in order togenerate the largest possible number of lightning strikes forexperimental purposes.– Site located at Privat d'Allier in Auvergne, FranceKeraunic level: 30Purpose of the experiments:- to qualify the lightning strike counters and- low-voltage arresters in situ- to qualify the resistance of the equipment to- triggered lightning strikes.– Site located at Camp Blanding (Florida/USA)Keraunic level: 80Purpose of the experiments:- to confirm the triggering time gain of the ESE air terminalscompared with single rod air terminals- to collect data with a view to improving the protectionmodels.Tests and research14 | ABB OPR lightning protection systemsLightning capture devicesLightning air terminalsEarly Streamer Emission Air Terminals (ESEAT) or SingleRod Air Terminals (SRAT).As a general rule, the lightning air terminal should culminate atleast two metres above the highest points of the building(s) tobe protected.Its location should therefore be determined relative to buildingsuperstructures: chimneys, machine and equipment rooms, flagpoles, pylons or aerials. Ideally, these vulnerable pointsshould be selected for lightning air terminal installation.The lightning air terminal may be raised by an extension mast.Our stainless steel interlocking extension masts can reachan overall height of 8.50 or 11 m including the lightning airterminal height. They have been specially designed to obviatethe need for guying. However, if guying is essential (e.g. whenthe conductor is fixed with a flat support on the roof waterproofing, or is exposed to particularly strong winds), the guysshould be made of Ø 5.6 fibre glass. When metal cables areused for guying, the lower anchoring points should be interconnectedwith the down conductor by a conductive materialof the same type. We offer a range of fixtures adapted to mostrequirements.Installation specifications are detailed in the individual productdata sheets.If several lightning air terminals (ESEAT or SRAT) are used inthe outside installation on the same structure, they should beconnected by a conductor, except when this has to pass anobstacle of more than 40 cm in height.D ≤ 40 cm: connect ESEATsD ≥ 40 cm: do not connect air terminalsWhen protecting open-air sites such as sports grounds, golfcourses, swimming pools, and camping sites, ESEATs areinstalled on special supports such as lighting masts, pylons, or any other nearby structures from which the conductor cancover the area to be protected.Our software OPR Designer is able to design a completelightning protection system with all installations details, listingof material, protections areas layout, tests certificates within acomplete technical document that is available for the client inpdf format.d ≤ 40 cm d ≤ 40 cm d ≤ 40 cmInterconnection rule when several ESEAT on the same roofABB OPR lightning protection systems | 15Lightning capture devicesSpecial casesAntennasBy agreement with the user of the antenna, the device canbe mounted on the antenna mast, provided that allowance ismade for a number of factors notably:– the lightning air terminal tip must culminate at least 2 mabove the antenna– the aerial coaxial cable is routed inside the antenna mast– the common supporting mast will no need guying– the connection to the down conductor will be made using aclamp fixed to the foot of the mast.This process, widely used today, offers three advantages:– technical (it earths the aerial itself)– visual (there is only one mast)– cost.To be noted that an ESEAT electronic generator cannot beused in an atmosphere where the temperature is greater than120°.Industrial chimneyESE air terminal:– the lightning air terminal should be mounted on an offsetmast (2CTH0HRI3501) as far as possible from smoke andcorrosive vapours– the mast should be fixed to 2 points as shown in the diagram.To be noted that an ESEAT electronic generator cannot beused in an atmosphere where the temperature is greater than120°.Single rod air terminal:The lightning air terminals (1 or 2 m) should be mounted onstainless steel supports (2CTH0HPS2630) to enable mountingat a 30° angle. They will be interconnected by a belt conductorpositioned 50 cm from the summit of the chimney.When using 1 m air terminal at least two points should beused and placed at intervals of no more than 2 m around theperimeter.When using strike points of at least 2 m in height, the numberof points should be calculated to cover the protection radius.SteepleThe lightning air terminal have been designed to carry roofornaments (rooster, weathervane, cardinal points, etc.).The down conductor is then fixed below the ornaments.2 mminimumESEATØ 35 mm stainless steelESEAT mast2CTH070011R0000500 mmantennasteel hoopsdownconductorESEAToffset mastdown conductorwind indicatorroostertightening screwcardinalpointsconnecting clamp750 mmESEAT basedown conductorESEAT16 | ABB OPR lightning protection systemsDown conductorsOverviewDown conductors should preferably be made with tin-platedred copper strips, 30 mm wide and 2 mm thick.Lightning is a high frequency current that flows along theperiphery of the conductors. For a like cross-section, a flatconductor has a greater periphery.An exception to the above rule is buildings with aluminiumcladding on which a copper down conductor might generatean electrolytic coupling phenomenon.Here a 30 x 3 mm aluminium strip should be used or bimetalconnection.In some cases where it is impossible to fix the copper strip, around Ø 8 mm tin-plated copper conductor. In the case wherethere is a need of mechanical movement of the down conductoruse a 30 x 3 mm flexible tin-platted copper braid.PathThe path should be planned to take account of the location ofthe earth termination. The path should be as straight and shortas possible avoiding any sharp bends or upturns. Curvatureradii should be no less than 20 cm. To divert the down conductorlaterally, 30 x 2 mm tin-plated red copper preformedbends should be used.The down conductor path should be chosen to avoid intersectionand to be routed along electrical ducts. Shieldingthe electrical ducts 1 m on each side can be done when it isimpossible to avoid crossing them. However when crossoverscannot be avoided, the conduit should be protected insidemetal sheeting extending by 1 m on either side of the crossover.This metal sheeting should be connected to the downconductor.However, in exceptional cases where an outside downconductor cannot be installed, the conductor may run downthrough a service duct, provided that this is used for no otherpurpose (and subject to agreement with the safety servicesand inspection organizations).When a building is fitted with a metallic external cladding orstone facing or in glass, or in the case of a fixed covering partof the facade, the down conductor can be installed on theconcrete facade or on the main structure, under the cladding.In this case, the conductive parts of the cladding must beconnected to the down conductor at the top and at thebottom.The down conductor, if not a copper one, shall be located atmore than 10 cm behind inflammable material of the outsidecladding if its cross section area if lower than 100 mm². Forcross section area of 100 mm² or greater, there is no need tokeep a distance between the down conductor and theflammable material.A specific calculation of the temperature increase may be performedto validate a different rule.The same requirements apply also to all inflammable materialeven on the roof (e.g. thatched roof).Indoor routingWhen a down conductor cannot be installed outside thestructure, it can be fitted inside on a part or on the full heightof the structure. In this case, the down conductor must beplaced inside a dedicated non flammable and insulating duct.The separation distance shall be calculated also for indoordown conductors in order to be able to determine the necessaryinsulation level of the dedicated duct.The building operator has to be aware of the resultingdifficulties to check and maintain the down conductors, and ofthe resulting risks of over voltages inside the building.Access of people to the specific cable channel should beavoided in stormy periods or measures of protection as peroutdoor down conductors should be fulfilled (see Annex DNF C 17-102 Vers September 2011) including equipotentialbondings of floors with the down conductor.Down-conductor bend shapesLd LdLdLLddL: length of the loop, in metersd: width of the loop, in metersThe risk of any dielectricbreakdown is avoided ifthe condition d>L/20is fulfilled.ABB OPR lightning protection systems | 17Down conductorsParapet wallsWhen the face of the parapet wall is less than or equal to40 cm, an upward section in the down conductor is allowedwith a maximum slope of no more than 45°. For parapet wallswith an upward section of more than 40 cm, space should beallowed or a hole drilled to accommodate a 50 mm minimumdiameter sheath and thereby avoid bypassing. If this is notpossible, supports of the same height as the parapet wallshould be installed to avoid an upturn.ConnectionThe lightning air terminal is connected to the downconductor by a connecting clamp that must be tightly securedon to the mast. The strip will be secured along the extensionmasts by stainless steel clamps. The conductors can beconnected together by coupling strips.FastenersWhatever the supporting medium the down conductor mustbe secured by at least 3 fasteners per linear meter. Insulatorsare used to distance the conductors and prevent contact witheasily flammable material (thatch or wood, for example).The fastener must be appropriate for the structure materialand installed so as not to impair watertightness and allow theconductor thermal extension.Test jointEach down conductor must be fitted with a test joint or connectionlink to enable measurement of the resistance of thelightning earth system alone and the electrical continuity of thedown conductor.The test coupling is usually placed about 2 m above groundlevel to make it accessible for inspection purposes only. To becompliant with standards, the test joint should be identified bythe words "lightning air terminal" and the "earth" symbol.On metal pylons, framework or cladding, the test joint shouldbe placed on the ground in inspection earth pit about 1 m fromthe foot of the metal wall to avoid distorting the resistancemeasurement of the earth connection by inevitably measuringthe electrical resistance on the other metallic networks in thebuilding.Protecting flatBetween the test joint and the ground, the strip is protectedby a 2 m galvanized or stainless steel sheet metal flat fixed by3 clamps supplied with the flat.The protecting flat can be bent to follow the profile of thebuilding.Warning Notice: Protection measures against step andtouch voltagesIn certain conditions, the vicinity of the down-conductors of anESE System, outside the structure, may be hazardous to lifestrip 30 x 2 mmcopper roundø 6 or 8 mm330lead play30 or 4030test jointprotectingathookdown conductorstriplead dowelcopper tape30 x 2 mm3 screw-in stainlesssteel clamps on the2 m of protecting atprotecting ateven if the ESE System has been designed and constructedaccording to the above-mentioned requirements.The hazard is reduced to a tolerable level if one of thefollowing conditions is fulfilled:The probability of persons approaching, or the duration oftheir presence outside the structure and close to the downconductors, is very low.

If none of these conditions isfulfilled, protection measures shall be adopted against injury toliving beings due to touch voltages as follows:– insulation of the exposed down-conductor is providedgiving a 100 kV, 1.2/50 μs impulse withstand voltage, e.g. at least 3 mm cross-linked polyethylene– physical restrictions and/or warning notices to minimize theprobability of down-conductors being touched.

If there is a ridge, the conductormust follow it.Air terminals are placed vertically at the highest and mostvulnerable points on the buildings (roof ridges, salient points, edges, corners, etc.).They are arranged at regular intervals around the periphery ofthe roof as follows:– the distance between two 30 cm air terminals should notexceed 15 m– the distance between two 50 cm air terminals should notexceed 20 m– strike air terminals not located on the outer polygon areconnected to the polygon as follows:- either by a conductor excluding any upturn if the air terminalsis less than 5 m from the polygon- or by two conductors in opposite directions forming atransversal section if the air terminals is located morethan 5 m from the polygon.On wallThe down conductors are placed on the corners and salientfeatures of the building in a layout that should be as symmetricaland regular as possible.The average distance between two adjacent down conductorsdepends on the required protection level.Protection level(IEC 62305-2)Distance between 2 downconductors (IEC 62305-3)Roof mesh size(IEC 62305-3)I 10 m 5 x 5II 10 m 10 x 10III 15 m 15 x 15IV 20 m 20 x 20ABB OPR lightning protection systems | 19Equipotential bondingOverviewWhen lightning current flows through a conductor, differencesin potential appear between the conductor and nearby metallicnetworks (steel framework, pipes, etc.) inside or outsidethe building. Dangerous sparks may be produced betweenthe two ends of the resulting open loop.There are two ways to avoid this problem:a) Establish an interconnection providing an equipotentialbond between the conductor and the metallic networksb) Allow a separation distance between the conductor and themetallic networks.The separation distance is the distance beyond which no dangeroussparks can be produced between the down conductorcarrying the lightning current and nearby metallic networks.Because it is often difficult to guarantee that the lightningprotection system is sufficiently isolated during installation orwill remain so in the event of structural changes, on-site work, etc., equipotential bonding is often preferred.There are, however, some cases in which equipotential bondingis not used (e.g. when there are flammable or explosivepiping net-works). In this case, the down conductors arerouted beyond the separation distance "s".Separation distance calculationS (m) = ki.kc.Lkmwhere:"kc" is a coefficient determined by the number of downconductors per ESEAT:kc = 1 for one down conductor, kc = 0.75 for two down conductors, kc = 0.6 for three conductors, kc = 0.41 for four ormore conductors." ki " is determined by the required protection level:ki = 0.08 for protection level 1 (high protection), for veryexposed or strategic buildingski = 0.06 for protection level 2 (reinforced protection, exposedbuilding)ki = 0.04 for protection level 3 & 4 (standard protection)"km" is related to the material situated between the twoloop ends:km : 1 for airkm = 0.5 for a solid material other than metal"L" is the length between the point at which proximity ismeasured and the point at which the metallic network isearthed or the nearest equipotential bonding point.S1L1L2S2air conditioningearthingbarExampleAn ESEAT with two down conductors protects a 20 m highbuilding with protection level I.– Question 1 : Should an air conditioning extractor locatedon the roof be interconnected if 3 m away from the downconductor? Length L1 = 25 m.Answer 1 : S1 = 0.08 x 0.75 x 25 / 1 = 1.5 mSince the distance (3 m) between the conductor and the airconditioningsystem is greater than the separation distance(1.5 meters), there is no need to interconnect this extractor.– Question 2 : Should the computer located in the building 3m away from the down conductor be interconnected withthe conductor, where L2 = 10 m?Answer 2 : S2 = 0.08 x 0.75 x 10 / 0.5 = 1.2 mSince the distance between the computer and the downconductor (3 m) is greater than the separation distance(1.2 m), there is no need to interconnect this computer.A tool is available that can be used to quickly calculate theseparation distances.20 | ABB OPR lightning protection systemsEquipotential bondingEquipotential bonding of external metallic networksThe equipotential bonding of external metallic networks is anintegral part of the outdoor lightning protection installation justlike the down conductors and their earths.All conductive metallic networks located at a distance of lessthan s (separation distance) from a conductor should beconnected to the conductor by a conductive material with alike cross-section.The aerial masts and small posts supporting electrical powerlines should be connected to the conductor via a mastarrester. Earthing systems embedded in walls should beconnected to the conductor if terminal connections have beenprovided.Equipotential bonding of internal metallic networksThe equipotential bonding of internal metallic networks is anintegral part of the indoor lightning protection installation.All conductive metallic networks in the structure (steelframeworks, ducts, sheathing, electrical raceways or telecommunicationcable trays, etc.) should be connected to theconductor. This is done by using a conductive material witha cross-section of at least 6 mm² for copper or 16 mm² forsteel to connect to equipotential bonding bars installed insidethe structure and connected in turn to the closest point of theearthing circuit.Unscreened telecommunication or electrical conductorsshould be bonded to the lightning protection system via surgearresters.Equipotential bonding of earthsThis is done by using a conductive material with across-section of at least 16 mm² for copper or 50 mm²for steel to connect bonding bar to earth termination system.interconnection withbuilding loop112233telephone line protectionlow voltage power supplyprotectionIT system protection44TV protectionESEAT OPRABB OPR lightning protection systems | 21Earth termination systemsOverviewEach down conductor in a lightning protection system must beconnected to an earth termination system which fulfils four conditions:– The earth termination resistance valueInternational standards stipulate an earth termination resistancevalue of less than 10 ohms.This value should be measured on the earth connection isolatedfrom any other conductive component.If the resistance value of 10 ohms cannot be achieved, the earthtermination is nonetheless considered compliant if it is made up ofat least 160 m (protection level 1) or 100 m (protection level 2, 3& 4) of conductors or electrodes, each section measuring no morethan 20 m.– Current carrying capacityThis is an often overlooked but essential aspect of lightningconduction. To minimise the earthing system impedance value, a parallel configuration of three electrodes is strongly recommendedinstead of just one excessively long electrode.– Equipotential bondingStandards require the equipotential bonding of lightningearth termination systems with the existing earthing systems.This must be done using 16 mm² (copper) or 50 mm² (steel)minimum cross section conductor.– Distance from buried utilitiesEarth termination should be at least 2 m (if soil resistivity is over500 ohms/m 5 m) distant from any buried metal pipe or electricalconduit, not connected to the main equipotential bonding of thestructure.Inspection earth pitThe connection parts of an earth termination system (duck's footconnector, earth rod, test joint) can be accessed in an inspection earthpit.Lightning air terminalsDucks foot connectorThe minimum earth termination system is made up of 25 m of30 x 2 mm tin-plated copper strip, split into 3 strands buried in3 trenches at a depth of 60 to 80 cm dug in a fan shape like a duck'sfoot: one end of the longest strand is connected to the test joint, thetwo other strands being linked to a special connection known as aduck foot's connector.Earth rodsWhen the site topography does not lend itself to the installation of aduck's foot as described above, an earth termination system can bedeveloped using at least 3 copper earth rods each with a minimumlength of 2 m, buried vertically in the ground; the rods should bespaced at intervals of about 2 m and at a mandatory distance of 1 mto 1.5 m from the foundations.protectionat30 x 2 mm down conductor6 to 9 m depending on soilresistance1 m from wall depth60 to 80 cm8 to 12 mstainlesssteel clampNB: the earth termination is covered by a red or orange warning gridDUCK'S FOOT EARTHTERMINATION SYSTEMduck'sfootconnectorDuck's foot earth termination systemIt is recommended to cover the earth termination system with a red or orange warningplastic mesh.protectionat30 x 2 mm strip2 m1 m from wall depth60 to 80 cmstainless steelclampNB: the earth termination is covered by a red or orange warning grid 2 m rodearth rod clampROD TRIANGLE EARTHTERMINATION SYSTEMRod triangle earth termination systemIt is recommended to cover the earth termination system with a red or orange warningplastic mesh.DUCK'S FOOT EARTH TERMINATIONSYSTEM WITH EARTH RODSprotectionat30 x 2 mm strip8 to 12 mdepth 6 to 9 m 60 to 80 cmduck'sfootconnectorstainlesssteel clampNB: the earth termination is covered by a red or orange warning gridrodearth rodclamp1 m from wallDuck's foot earth termination system with earth rodsIt is recommended to cover the earth termination system with a red or orange warningplastic mesh.22 | ABB OPR lightning protection systemsEarth termination systemsCombinedIf the soil type is not altogether suitable for a duck's foot connector, a combination of duck's foot and earth rods will significantlyenhance protection (better earth resistance). In this case, the endof each duck foot connector strand is connected to an earth rod.Meshed conductorsDuck's foot connectorThe earth connection is made up of 3 conductors each 3 mminimum in length, buried horizontally at a depth of 60 to 80 cm.One of the strips is connected to one end of the test joint; theother two splay out at an angle of 45° on either side of this centralstrand and are coupled to it with a special connector known as aduck's foot connector. The resistance value must be less than 10ohms. If the resistance value of 10 ohms cannot be achieved, theearth termination is nonetheless considered compliant if it is madeup of at least 160 m of electrode in level 1, 100 m in level 2 and10 m in level 3 & 4.Earth rodsThe earth connection is made up of 2 spiked vertical rods at least2 m in length, connected to each other and to the down conductor, and at least 2 m from each other. The rods should be 1 m to1.5 m from the foundations. The earth termination systems in abuilding should be connected together with a conductor with thesame cross-section and of the same type as the down conductors.Where there is an existing entrenched earth protection loopin the foundations for the building's 2 m flat electrical installations, there is no need to create a new loop: the earth terminations cansimply 0.6 m be interconnected by a tin-plated 30 x 2 mm copperstrip. The resistance value must be less than 10 ohms. If the resistancevalue of 10 ohms cannot be achieved, the earth terminationis nonetheless considered compliant if it is made up of at least160 m (80 m if vertical rods) of electrode in level 1, 100 m (50 m ifvertical rods) in level 2 and 10 m (5 m if vertical rods) in level 3 & 4.Earthing system equipotential bondingWhen the protected building or area has an existing earth terminationsystem for the electrical installations, the lightning earthtermination systems should be connected to it.This interconnection should be made to the earthing circuit at theclosest point to the down conductor.When this is impossible in an existing building, the interconnectionshould be made to the earth plate. In this case, the interconnectingconductor should be constructed such that no currents areinduced in nearby equipment cables.In all cases, the interconnection should include a device that canbe disconnected to enable measurements of the resistance of thelightning earth termination system.This device can be made up of either an interconnection box forequipotential bonding fixed to the main wall of the building, or anequipotential bonding bar located in an inspection earth pit.Duck's foot system for a meshed cageIt is recommended to cover the earth termination system with a red or orange warningplastic mesh.protectionat30 x 2 mm strip3 m1 m from wall depth60 to 80 cm4 mstainlesssteel clampNB: the earth termination is covered by a red or orange warning gridDUCK'S FOOT SYSTEMFOR A MESHED CAGEduck'sfootconnector2 m0.6 m2 mtestjointprotectionat2 rodsD: down conductor of a lightning air terminalB: entrenched building loopP: lightning conductor earth termination systemtestjointdisconnectableconnectionDPBABB OPR lightning protection systems | 23Inspection ESEAT maintenanceThe current standards NF C 17-102 September 2011 editionrecommends regular, periodical inspections of the lightningprotection system.The following schedules are recommended:Protection level Visual inspection(year)Complete inspection(year)Critical system completeinspection (year)I and II 1 2 1III and IV 2 4 1Note: Critical systems shall be defined by laws or end users.A lightning protection system should also be inspected wheneverthe protection structure is modified, repaired or when thestructure has been struck by lightning.Lightning strikes can be recorded by a lightning strike counterinstalled on one of the down conductors.ESEAT maintenance kit, a unique solutionWith its experience of ESEAT development and specialtesting processes, ABB offers a simple and complete solution:a telescopic 8 m pole supplied with a portable test case toenable simple in situ inspections.The device can be used without dismantling the ESEAT.The following aspects of an ESE System installationshould be inspected (see NF C 17-102 September 2011edition pagraph 8)A visual inspection should be performed to make sure that:– no damage related to lightning has been noted– integrity of ESE System has not been modified– no extension or modification of the protected structureneeds the installation of additional lightning protectionmeasures– the electrical continuity of visible conductors is correct– all component fasteners and mechanical protectors are ingood condition– no parts have been weakened by corrosion– the separation distance is respected and there are enoughequipotential bondings and their condition is correct– SPD end of life indicator is correct– maintenance operations results are checked and recordedComplete verification includes visual verification and thefollowing measurements to check:– the electrical continuity of hidden conductors– the earth termination system resistance values (anyvariation with regards to initial values > 50 % should beanalysed)– properly working of ESEAT according to manufacturerprocedure.NOTE: High frequency earth system measurement is feasible during installation or inmaintenance operation in order to check the coherence between the needs and theinstalled earth system.The findings of each scheduled inspection should be recordedin a detailed report stating the required corrective measures.Any faults identified in a scheduled inspection should becorrected as soon as possible in order to maintain optimallightning protection.Initial verification should be performed once the ESE systeminstallation is completed in order to make sure that it complieswith the NF C 17-102 standard requirements.24 | ABB OPR lightning protection systemsLightning air terminal rangeESEAT typical installation on masonry buildingOPR lightning conductorp.26Coupling accessoriesp.36Hooks p.37Test joint p.39Duck foot connectorp.41Lightning strokecounter and recorderp.43Extension mast p.31Conductor supportingstud p.37Ruberalu bracketsp.37Antenna mastarrester p.43Boltedbrackets p.33Protecting flatp.39Equipotential boxp.39Type 1 surge protective devicehighly recommendedABB OPR lightning protection systems | 25Lightning air terminal rangeESEAT typical installation on metal claddingOPR lightningconductor p.26Threaded basesp.35Test joint p.39Interconnection boxp.39Lightning strokecounter p.43Stainless steel clipp.37Protecting flatp.39Water deflecting conesp.35WaterproofStainless steel clipp.37Type 1 surge protective devicehighly recommended26 | ABB OPR lightning protection systemsLightning air terminal range - Early Streamer EmissionOPR, the high pulse voltage, initiation advance lightningair terminalABB continues to innovate, and has developed a new generationof lightning devices. The new OPR range with increasedinitiation advance performances, represents further progressin terms of protection, operating autonomy and ease of maintenance.These advancements reinforce ABB's position asInternational leader in direct lightning protection with over 200000 installations throughout the world.ABB manufacturing qualityThe enviable reputation of the OPR has been earned throughmaintaining a consistently high quality in manufacture. Beforeleaving the factory, each OPR has been tested for installationbreakdown at high voltage, and subjected to a currenttest that ensures its performance when conducting lightningdischarges. The high voltage output pulses at the OPR arealso examined to verify correct amplitude and frequency. TheOPR is built to withstand the arduous conditions encounteredin service, and its ongoing performance can be monitoredsimply and quickly using the OPR test set.The advantage of initiation advanceThe unique efficiency of the OPR lightning air terminal isbased on a specific initiation advance, well before the naturalformation of an upward leader, the OPR generates a leaderthat rapidly propagates to capture the lightning and direct it toearth. Validated in the laboratory, this gain in time relative tothe simple rod provides additional essential protection.Complete autonomyDuring a storm the ambient electric field may rise to between10 to 20 kV/m. As soon as the field exceeds a thresholdrepresenting the minimum risk of a lightning strike, the OPRlightning terminal is activated. It draws its energy from theambient electric field the energy required to generate highvoltage pulses, creating and propagating an upward leader.No other power sources are required, and no radioactivecomponents are used.Upward leaders Return arc Meeting pointA B C DOPR Upward leaders Meeting pointA B C DABB OPR lightning protection systems | 27RodCheck system: visual strike indicatorThe aim of the RodCheck system is to give visual information on the intensity of the lightning current caughtby the OPR even from a long distance.We need to keep in mind that the lightning rod is a security device that permits to limit risk and thereforecontributes to the safety of the people. Indeed a lightning impact may lead to explosion, to fire and consequentlybe a risk for the people within the structure.As for any security device, it is important to figure out directly its degree of aging, which is linked to the lightningstrike current to which it has been subjected.On many sites lightning rods are usually equipped with counters that detect the flow of current without necessarilygiving information about its intensity.Only a digital counter could give such characteristics, but it would undoubtedly increase the price of theoverall installation.On the other hand, the new edition of the NF C 17-102 also states that from January 2009 it has been compulsoryto have two down conductors per ESEAT. Therefore, as the counters are usually placed only on oneof the two down conductors, they don't record the entire value of the current.The RodCheck system has been developed so as to solve this specific security issue and it provides anestimate of the intensity of the lightning strike at first glance.Thanks to the new RodCheck technology, the OPR considerably reinforces and improves the security of sitesand people and provides the right answer to a perfectly justified question: "Has the lightning rod been deeplyhit and is it necessary to check the installation?"This visual indicator is made of a UV resistant EPDM shell, mounted directly on the OPR external spark gap.RodCheck has not beenhit by a lightning strokeRodCheck after lightningstroke of few kARodCheck after severalstrokes or one of more than40 kALightning air terminal rangeEarly Streamer Emission Air Terminal - ESEAT1 2 3In the examples 2 and 3 we recommend performing a test of the OPR's electronics and afterwards the redring may be put back in the initial position (example 1).As long as there is no indication of strike it is not necessary to test the generator. But on the other hand, westrongly recommend a complete check of the lighting rod OPR, including the check of its internal electronicsystem in case of a lightning impact. An 8 m high pole connected to a test case is needed to carry out thetest of the generator.28 | ABB OPR lightning protection systemsLightning air terminal rangeEarly Streamer Emission Air Terminal - ESEATTypical applicationsIndustrial sites, buildings, warehouses, where a large protection area is needed.Ordering detailsOPR∆T Description Type Order code Ean code Pkg(pcs)Weight(1 pce)µs kg30 OPR 30 IMH3000 2CTB899800R7000 3660308514172 1 2.40045 OPR 45 IMH4500 2CTB899800R7500 3660308514706 1 2.40060 OPR 60 IMH6000 2CTB899800R7100 3660308514189 1 2.400Mast to be ordered separately.Maximum operating temperature: 120 °C.OPR radius of protectionLevel of protection I (r = 20 m) II (r = 30 m) III (r = 45 m) IV (r = 60 m)Type OPR 30 OPR 45 OPR 60 OPR 30 OPR 45 OPR 60 OPR 30 OPR 45 OPR 60 OPR 30 OPR 45 OPR 60h (m) Radius of protection Rp (m)2 19 25 31 22 28 35 25 32 39 28 36 433 29 38 47 33 42 52 38 48 58 43 57 644 38 51 63 44 57 69 51 65 78 57 72 855 48 63 79 55 71 86 63 81 97 71 89 1076 48 63 79 55 71 87 64 81 97 72 90 1078 49 64 79 56 72 87 65 82 98 73 91 10810 49 64 79 57 72 88 66 83 99 75 92 10915 50 65 80 58 73 89 69 85 101 78 95 11120 50 65 80 59 74 89 71 86 102 81 97 11345 43 65 76 58 75 89 75 90 105 89 104 11950 40 65 74 57 75 88 75 90 105 89 104 12055 36 65 72 55 75 86 74 90 105 90 105 12060 30 65 69 52 75 85 73 90 104 90 105 120Note: the optimized radius of protection is reached when placing the ESE lightning conductor at 5 m above the highest point of the structure to protect.

This typeof cloud is very extensive, both horizontally (about 10 km indiameter) and vertically (up to 15 km). Its highly characteristicshape is often compared with the profile of an anvil of whichit displays the upper and lower horizontal planes. The existenceof extreme temperature gradients in a cumulonimbus(the temperature can drop to -65 °C at the top) generatesvery rapid ascending air currents, and results in the electricalenergisation of the water particles.In a typical storm cloud, the upper part, consisting of icecrystals, is normally positively charged, whilst the lower part, consisting of water droplets, is negatively charged. Consequently, the lower part of the cloud causes the developmentof electrically opposite charges (i.e. positive over the part ofthe ground nearby).Thus the cumulonimbus formation constitutes a sort of hugeplate /ground capacitor whose median distance can oftenreach 1 to 2 km. The atmospheric electrical field on theground, about 600 V/m in fine weather is reversed and canreach an absolute value of 15 to 20 kV/m when a grounddischarge is imminent (the lightning stroke).Before and during the appearance of the lightning stroke, discharges can be seen both within the cloud and betweenclouds.LightningAccording to the direction in which the electrical dischargedevelops (downward or upward), and the polarity of thecharges it develops (negative or positive), four classes ofcloud-to-ground lightning stroke can be distinguished. Inpractice, lightning strokes of the descending and negativetype are by far the most frequent: it is estimated that on plainsand in our temperate zones, they account for 96 % of allcloud / ground discharges.Mechanism of a lightning strokeIt is impossible to discern the individual phases of the lightningstroke by simple visual observation. This can only bedone with high-speed cameras. Most lightning bolts exhibitthe following phenomena: a leader leaves a point in thecloud and travels about 50 m at a very high speed of around50 000 km/s. A second leader then leaves the same point, follows the previous path at comparable speed, goes beyondthe final point of the first leader by an approximately identicaldistance, then disappears in turn.The process is repeated until the tip of the last leader reachesa point a few dozen metres, or even just a few metres aboveground level.The ascending jets then converge, producing a return strokefrom the ground towards the cloud (the upward streamer) duringwhich the electric current circulates: The convergence ofthese two phenomena produces the main discharge, whichmay be followed by a series of secondary discharges, passingunbroken along the channel ionised by the main discharge.In an average negative lightning stroke, the maximum currentis around 35 000 A.----------- - - -+++ ++++ + ++++++++++ + + + + + + + + + + + + + + + + + + +ABB OPR lightning protection systems | 3Lightning protection technologiesThe effects of lightningThe effects of lightning are those of a high-strength impulsecurrent that propagates initially in a gaseous environment (theatmosphere), and then in a solid, more or less conductivemedium (the ground):– visual effects (flash): caused by the Townsend avalanchemechanism– acoustic effects: caused by the propagation of a shockwave (rise in pressure) originating in the discharge path;this effect is perceptible up to a range of around 10 km– thermal effect: heat generated by the Joule effect in theionised channel– electrodynamic effects: these are the mechanical forces appliedto the conductors placed in a magnetic field createdby the high voltage circulation. They may result in deformations– electrochemical effects: these relatively minor effects areconveyed in the form of electrolytic decomposition throughthe application of Faraday's law– induction effects: in a variable electroma-gnetic field, everyconductor harnesses induced current– effects on a living being (human or animal): the passage ofa transient current of a certain r.m.s value is sufficient toincur risks of electrocution by heart attack or respiratoryfailure, together with the risk of burns.Lightning causes two major types of accidents:– accidents caused by a direct stroke when the lightningstrikes a building or a specific zone. This can cause considerabledamage, usually by fire. Protection against thisdanger is provided by lightning air terminal systems– accidents caused indirectly, as when the lightning strikes orcauses power surges in power cables or transmission links.Hence the need to protect with SPD the equipment at riskagainst the surge voltage and indirect currents generated.Protection against direct lightning strokeTo protect a structure against lightning strokes, a preferredimpact point is selected to protect the surrounding structureand conduct the flow of the electric current towards theground, with minimal impedance on the path followed bythe lightning. Four types of protection systems meet theserequirements.Protection systems StandardsEarly streamer emission air terminal - France: NF C 17-102 (September 2011 edition)- Argentina: IRAM 2426- Spain: UNE 21186- Macedonia: MKS N.B4 810- Portugal: NP 4426- Romania: I-20- Slovakia: STN 34 1391- Serbia: JUS N.B4.810Single rods air terminals IEC 62 305-3Meshed cages IEC 62 305-3Stretched wires IEC 62 305-34 | ABB OPR lightning protection systemsLightning protection system with early streamer emissionair terminal (ESEAT)These state-of-the-art technologies have been designed onthe basis of a series of patents registered jointly by HELITAand the French National Scientific Research Centre (CNRS).The OPR is equipped with an electronic device which is highpulse voltage of known and controlled frequency and amplitudeenabling the early formation of the upward leader which isthen continuously propagated towards the downward leader.This anticipation in the upward leader formation is essentialwith regard to the last scientific knowledge on the lightningattachment that acknowledge the fact that this one resultsfrom an upward leader competition. Today the upward leadercompetition is internationally recognized thanks to high speedcameras pictures of this phenomenon of attachment and to itsdigital simulation.The OPR draws its energy from the ambient electrical fieldduring the storm. After capturing the lightning stroke, the OPRdirects it towards the down conductors to the ground where itis dissipated.Triggering time of an ESEAT1 2Lightning protection technologiesABB OPR lightning protection systems | 5The early streamer emission (ESE) conceptDuring a storm, when the propagation field conditions arefavourable, the OPR first generates an upward leader. Thisleader from the OPR tip propagates towards the downwardleader from the cloud at an average speed of 1 m/µs.The triggering time ∆T (µs) is defined as the mean gain atthe sparkover instant (continuous propagation of the upwardleader) obtained with an ESE air terminal compared with asingle rod air terminal exposed to the same conditions. ∆T ismeasured in the high-voltage laboratory, all tests are definedin appendix C of the French standard NF C 17-102.The triggering time instance gain ∆T is associated with atriggering time distance gain ∆L.∆L = v. ∆T, where:– ∆L (m): gain in lead distance or sparkover distance– v (m/µs): average speed of the downward tracer (1 m/µs).– ∆T (µs): gain in sparkover time of the upward leadermeasured in laboratory conditions.OPR air terminals are especially effective for the protectionof classified industrial sites, administrative or public buildings, historical monuments and open-air sites such as sportsgrounds.Lightning protection technologies6 | ABB OPR lightning protection systemsLightning protection technologiesLightning protection system with meshed cagesThis principle consists of dividing up and more easily dissipating thelightning current by a network of conductors and earths.A meshed cage installation has multiple down conductors andconsequently provides very effective protection for buildingsthat house equipment sensitive to electromagnetic disturbance.This is because the lightning current is divided among the downconductors and the low current circulating in the mesh creates verylittle disturbance by induction.A meshed cage installation is made up of:– devices to capture the atmospheric discharges consisting ofstrike points– roof conductors– down conductors– protection measures against injuries to leaving being due totouch and step voltages (e.g. warning notice)– an equipotential bonding between each earth and the generalearthing circuit of the structure; this one must be disconnectable.Installation conditionsLightning Protection System with an ESEAT is made of:– an Early Streamer Emission Air Terminal and its extension mast– two down conductors, or in case of several ESEAT oneconductor per ESEAT– a connecting link or test joint for each down conductor toenabling the earth resistance to be verified– a protecting flat to protect the down conductor for the last twometers above ground level– an earth designed to dissipate the lightning currents at thebottom of each down conductor– an equipotential bonding between each earth and the generalearthing circuit of the structure; this one must be disconnectable– protection measures against injuries to leaving being due totouch and step voltages (e.g. warning notice).Lightning protection system with single rod air terminalBy protruding upwards from the building, they are likely to triggerthe release of ascending streamers and thus be selected asimpact points by lightning strokes occurring within the vicinity of thestructure.This type of protection is especially recommended for radio stationsand antenna masts when the area requiring protection is relativelysmall.A single rod air terminal protection is made up of:– a rod lightning air terminal and its extension mast– two down conductors– a connection link or test joint on each down conductor to checkthe conductor earth resistance– a protecting flat to protect the down conductor for the last twometers above ground level– an equipotential bonding between each earth and the generalearthing circuit of the structure; this one must be disconnectable– protection measures against injuries to leaving being due totouch and step voltages (eg warning notice).ABB OPR lightning protection systems | 7Lightning protection technologiesStretched wiresThis system is composed of one or several conductor wiresstretched above the protected installation. The protection area isdetermined by applying the electro-geometrical model.The conductors must be earthed at each end.A stretched wire installation requires a thorough preliminary studyto consider issues such as mechanical strength, the type ofinstallation, and the insulation distances.This technology is used to protect ammunition depots and as ageneral rule in circumstances where the site cannot be protectedby using a building structure to support the conductors thatconvey the lightning currents to the earth.Protection against indirect lightning stroke effectsWhen lightning strikes cables and transmission lines (H.F. coaxialcables, telecommunication lines, power cables), a voltage surgeis propagated and may reach equipment in the surrounding. Thisvoltage surge can also be generated by induction due to theelectromagnetic radiation of the lightning flash.This can have many consequences: premature componentageing, destruction of printed circuit boards or component plating, equipment failure, data loss, programs hanging, line damage, etc. This is why you need to use Surge Protective Devices toprotect equipment liable to be affected by lightning strikes.The use of Surge Protective Devices is highly recommendedwhen the building is fitted with an external lightning protection. Atype 1 SPD is highly recommended or even mandatory in somecountries. A good protection is made in step with one type 1 fittedin the MDB when the SDB are fitted with type 2 SPDs.Early Streamer EmissionAir TerminalMDBSDB - SubDistribution BoardSDBTelephone inputMainpower inputMDB - MainDistribution BoardTelecomboardEquipotential bonding of metal partsDuring a lightning stroke or even as a result of indirect effects, equipotential bonding defects can, by differences in potential, generate sparkover causing risk for human being or fire into thestructure.This is why it is an essential part of effective lightning protection toensure that a site's equipotential bonding is effective and in goodcondition.The necessity of an electrical insulation between the air terminationor the down-conductor and the structural metal parts, themetal installations and the internal systems can be achieved byproviding a separation distance "s" between the parts. 8 | ABB OPR lightning protection systemsLightning protection risk analysisRisk analysisAll lightning protection standards recommend a preliminarylightning risk analysis in three parts:– lightning risk evaluation– protection level selection– protection device definition.We have developed a software based on the calculations ofthe IEC 62305-2 or NF C 17-102 (appendix A) in order to giveyou an easy and accurate solution regarding the risk analysisof any installation you wish to protect.Lightning flash density map (flashes per km² per year)Protection device definitionIt is advisable to take into account the technical and architecturalconstraints when configuring the different components ofthe protection device.To facilitate your preliminary studies, we will provide a questionnairein which the minimum required information can beentered, and a calculation software package. 2 < Ng < 8 8 < Ng < 18ABB OPR lightning protection systems | 9Lightning protection technical studyOPR Designer softwareABB is happy to provide you with a complete new software in the field of lightningprotection.With a very simple approach you can create your technical study in one click!You can either draw, import file (AutoCAD, pictures…)and from that point get a complete bill of material(air terminals, down conductors, fixing accessoriesand earthing system), the positioning of the lightningprotection system on the structure.The solution is given in a complete pdf file that includes :– protected areas– lightning air terminals positioning– complete bill of material– detailed bill of material per building– catalogue pages for each component– test certificatesThis software is so far available in English, French, Spanish, Russian and Lithuanian version.You may download OPR designer at the following address :http://www.web-emedia.com/opr/10 | ABB OPR lightning protection systemsProcedure for measuring the Early Streamer Emission of an ESEair terminal according to standard NF C 17-102 appendix CThis test procedure consists in evaluating the triggering timeof an Early Streamer Emission (ESEAT) compared with thereference Single Rod Air Terminal (SRAT) in high voltage laboratoryconditions. 50 shocks are applied to the single rod air terminalin the first configuration, then to the early streamer emission airterminal in a second configuration.Simulation of natural conditionsNatural conditions can be simulated in a laboratory by superimposinga permanent field and an impulse field associated with a plate /ground platform area (H). The tested lightning air terminal is placedon the ground, beneath the centre of this platform. In the experiment, the height H = 6 m, and the lightning air terminal heighth = 1.5 m.Electrical conditionsThe permanent field caused by the charge distribution in thecloud is represented by a negative DC voltage of -20 to -25 kV/m(simulating a negative field of around -20 to -25 kV/m) applied tothe upper plate. The impulse field caused by the approach of thedownload leader is simulated with a negative polarity wave appliedto the platform. The rise time of the wave Tm is 650 µs.

For this purpose, weare using high speed cameras, lightning current recorders aswell as field and light recorders.Another in situ test runs at the Taoulet station 2300 m to verifythat theoretical values announced are also validated in realconditions.A constant partnership with scientists permits to follow thesein situs sites and lead to fundamental research on lighting.

Ideally, these vulnerable pointsshould be selected for lightning air terminal installation.The lightning air terminal may be raised by an extension mast.Our stainless steel interlocking extension masts can reachan overall height of 8.50 or 11 m including the lightning airterminal height. They have been specially designed to obviatethe need for guying. However, if guying is essential (e.g. whenthe conductor is fixed with a flat support on the roof waterproofing, or is exposed to particularly strong winds), the guysshould be made of Ø 5.6 fibre glass. When metal cables areused for guying, the lower anchoring points should be interconnectedwith the down conductor by a conductive materialof the same type. We offer a range of fixtures adapted to mostrequirements.Installation specifications are detailed in the individual productdata sheets.If several lightning air terminals (ESEAT or SRAT) are used inthe outside installation on the same structure, they should beconnected by a conductor, except when this has to pass anobstacle of more than 40 cm in height.D ≤ 40 cm: connect ESEATsD ≥ 40 cm: do not connect air terminalsWhen protecting open-air sites such as sports grounds, golfcourses, swimming pools, and camping sites, ESEATs areinstalled on special supports such as lighting masts, pylons, or any other nearby structures from which the conductor cancover the area to be protected.Our software OPR Designer is able to design a completelightning protection system with all installations details, listingof material, protections areas layout, tests certificates within acomplete technical document that is available for the client inpdf format.d ≤ 40 cm d ≤ 40 cm d ≤ 40 cmInterconnection rule when several ESEAT on the same roofABB OPR lightning protection systems | 15Lightning capture devicesSpecial casesAntennasBy agreement with the user of the antenna, the device canbe mounted on the antenna mast, provided that allowance ismade for a number of factors notably:– the lightning air terminal tip must culminate at least 2 mabove the antenna– the aerial coaxial cable is routed inside the antenna mast– the common supporting mast will no need guying– the connection to the down conductor will be made using aclamp fixed to the foot of the mast.This process, widely used today, offers three advantages:– technical (it earths the aerial itself)– visual (there is only one mast)– cost.To be noted that an ESEAT electronic generator cannot beused in an atmosphere where the temperature is greater than120°.Industrial chimneyESE air terminal:– the lightning air terminal should be mounted on an offsetmast (2CTH0HRI3501) as far as possible from smoke andcorrosive vapours– the mast should be fixed to 2 points as shown in the diagram.To be noted that an ESEAT electronic generator cannot beused in an atmosphere where the temperature is greater than120°.Single rod air terminal:The lightning air terminals (1 or 2 m) should be mounted onstainless steel supports (2CTH0HPS2630) to enable mountingat a 30° angle. They will be interconnected by a belt conductorpositioned 50 cm from the summit of the chimney.When using 1 m air terminal at least two points should beused and placed at intervals of no more than 2 m around theperimeter.When using strike points of at least 2 m in height, the numberof points should be calculated to cover the protection radius.SteepleThe lightning air terminal have been designed to carry roofornaments (rooster, weathervane, cardinal points, etc.).The down conductor is then fixed below the ornaments.2 mminimumESEATØ 35 mm stainless steelESEAT mast2CTH070011R0000500 mmantennasteel hoopsdownconductorESEAToffset mastdown conductorwind indicatorroostertightening screwcardinalpointsconnecting clamp750 mmESEAT basedown conductorESEAT16 | ABB OPR lightning protection systemsDown conductorsOverviewDown conductors should preferably be made with tin-platedred copper strips, 30 mm wide and 2 mm thick.Lightning is a high frequency current that flows along theperiphery of the conductors. For a like cross-section, a flatconductor has a greater periphery.An exception to the above rule is buildings with aluminiumcladding on which a copper down conductor might generatean electrolytic coupling phenomenon.Here a 30 x 3 mm aluminium strip should be used or bimetalconnection.In some cases where it is impossible to fix the copper strip, around Ø 8 mm tin-plated copper conductor. In the case wherethere is a need of mechanical movement of the down conductoruse a 30 x 3 mm flexible tin-platted copper braid.PathThe path should be planned to take account of the location ofthe earth termination. The path should be as straight and shortas possible avoiding any sharp bends or upturns. Curvatureradii should be no less than 20 cm. To divert the down conductorlaterally, 30 x 2 mm tin-plated red copper preformedbends should be used.The down conductor path should be chosen to avoid intersectionand to be routed along electrical ducts. Shieldingthe electrical ducts 1 m on each side can be done when it isimpossible to avoid crossing them. However when crossoverscannot be avoided, the conduit should be protected insidemetal sheeting extending by 1 m on either side of the crossover.This metal sheeting should be connected to the downconductor.However, in exceptional cases where an outside downconductor cannot be installed, the conductor may run downthrough a service duct, provided that this is used for no otherpurpose (and subject to agreement with the safety servicesand inspection organizations).When a building is fitted with a metallic external cladding orstone facing or in glass, or in the case of a fixed covering partof the facade, the down conductor can be installed on theconcrete facade or on the main structure, under the cladding.In this case, the conductive parts of the cladding must beconnected to the down conductor at the top and at thebottom.The down conductor, if not a copper one, shall be located atmore than 10 cm behind inflammable material of the outsidecladding if its cross section area if lower than 100 mm². Forcross section area of 100 mm² or greater, there is no need tokeep a distance between the down conductor and theflammable material.A specific calculation of the temperature increase may be performedto validate a different rule.The same requirements apply also to all inflammable materialeven on the roof (e.g. thatched roof).Indoor routingWhen a down conductor cannot be installed outside thestructure, it can be fitted inside on a part or on the full heightof the structure. In this case, the down conductor must beplaced inside a dedicated non flammable and insulating duct.The separation distance shall be calculated also for indoordown conductors in order to be able to determine the necessaryinsulation level of the dedicated duct.The building operator has to be aware of the resultingdifficulties to check and maintain the down conductors, and ofthe resulting risks of over voltages inside the building.Access of people to the specific cable channel should beavoided in stormy periods or measures of protection as peroutdoor down conductors should be fulfilled (see Annex DNF C 17-102 Vers September 2011) including equipotentialbondings of floors with the down conductor.Down-conductor bend shapesLd LdLdLLddL: length of the loop, in metersd: width of the loop, in metersThe risk of any dielectricbreakdown is avoided ifthe condition d>L/20is fulfilled.ABB OPR lightning protection systems | 17Down conductorsParapet wallsWhen the face of the parapet wall is less than or equal to40 cm, an upward section in the down conductor is allowedwith a maximum slope of no more than 45°. For parapet wallswith an upward section of more than 40 cm, space should beallowed or a hole drilled to accommodate a 50 mm minimumdiameter sheath and thereby avoid bypassing. If this is notpossible, supports of the same height as the parapet wallshould be installed to avoid an upturn.ConnectionThe lightning air terminal is connected to the downconductor by a connecting clamp that must be tightly securedon to the mast. The strip will be secured along the extensionmasts by stainless steel clamps. The conductors can beconnected together by coupling strips.FastenersWhatever the supporting medium the down conductor mustbe secured by at least 3 fasteners per linear meter. Insulatorsare used to distance the conductors and prevent contact witheasily flammable material (thatch or wood, for example).The fastener must be appropriate for the structure materialand installed so as not to impair watertightness and allow theconductor thermal extension.Test jointEach down conductor must be fitted with a test joint or connectionlink to enable measurement of the resistance of thelightning earth system alone and the electrical continuity of thedown conductor.The test coupling is usually placed about 2 m above groundlevel to make it accessible for inspection purposes only. To becompliant with standards, the test joint should be identified bythe words "lightning air terminal" and the "earth" symbol.On metal pylons, framework or cladding, the test joint shouldbe placed on the ground in inspection earth pit about 1 m fromthe foot of the metal wall to avoid distorting the resistancemeasurement of the earth connection by inevitably measuringthe electrical resistance on the other metallic networks in thebuilding.Protecting flatBetween the test joint and the ground, the strip is protectedby a 2 m galvanized or stainless steel sheet metal flat fixed by3 clamps supplied with the flat.The protecting flat can be bent to follow the profile of thebuilding.Warning Notice: Protection measures against step andtouch voltagesIn certain conditions, the vicinity of the down-conductors of anESE System, outside the structure, may be hazardous to lifestrip 30 x 2 mmcopper roundø 6 or 8 mm330lead play30 or 4030test jointprotectingathookdown conductorstriplead dowelcopper tape30 x 2 mm3 screw-in stainlesssteel clamps on the2 m of protecting atprotecting ateven if the ESE System has been designed and constructedaccording to the above-mentioned requirements.The hazard is reduced to a tolerable level if one of thefollowing conditions is fulfilled:The probability of persons approaching, or the duration oftheir presence outside the structure and close to the downconductors, is very low.

If none of these conditions isfulfilled, protection measures shall be adopted against injury toliving beings due to touch voltages as follows:– insulation of the exposed down-conductor is providedgiving a 100 kV, 1.2/50 μs impulse withstand voltage, e.g. at least 3 mm cross-linked polyethylene– physical restrictions and/or warning notices to minimize theprobability of down-conductors being touched.

The counter is connected inserial on the down conductor.Lightning stroke counter and recorder is used to store dateand time of the impact as well as lightning current values.Meshed conductorsOn roofIs carried on the roof meshes with conductors of which thewidth depends on the level of protection and those ones mustnot be greater than 20 m as follows:It is primarily a closed polygon whose perimeter is adjacentthe periphery of the roof, this polygon is then complete bytransverse conductors to satisfy the condition on the maximumwidth of the meshes. If there is a ridge, the conductormust follow it.Air terminals are placed vertically at the highest and mostvulnerable points on the buildings (roof ridges, salient points, edges, corners, etc.).They are arranged at regular intervals around the periphery ofthe roof as follows:– the distance between two 30 cm air terminals should notexceed 15 m– the distance between two 50 cm air terminals should notexceed 20 m– strike air terminals not located on the outer polygon areconnected to the polygon as follows:- either by a conductor excluding any upturn if the air terminalsis less than 5 m from the polygon- or by two conductors in opposite directions forming atransversal section if the air terminals is located morethan 5 m from the polygon.On wallThe down conductors are placed on the corners and salientfeatures of the building in a layout that should be as symmetricaland regular as possible.The average distance between two adjacent down conductorsdepends on the required protection level.Protection level(IEC 62305-2)Distance between 2 downconductors (IEC 62305-3)Roof mesh size(IEC 62305-3)I 10 m 5 x 5II 10 m 10 x 10III 15 m 15 x 15IV 20 m 20 x 20ABB OPR lightning protection systems | 19Equipotential bondingOverviewWhen lightning current flows through a conductor, differencesin potential appear between the conductor and nearby metallicnetworks (steel framework, pipes, etc.) inside or outsidethe building. Dangerous sparks may be produced betweenthe two ends of the resulting open loop.There are two ways to avoid this problem:a) Establish an interconnection providing an equipotentialbond between the conductor and the metallic networksb) Allow a separation distance between the conductor and themetallic networks.The separation distance is the distance beyond which no dangeroussparks can be produced between the down conductorcarrying the lightning current and nearby metallic networks.Because it is often difficult to guarantee that the lightningprotection system is sufficiently isolated during installation orwill remain so in the event of structural changes, on-site work, etc., equipotential bonding is often preferred.There are, however, some cases in which equipotential bondingis not used (e.g. when there are flammable or explosivepiping net-works). In this case, the down conductors arerouted beyond the separation distance "s".Separation distance calculationS (m) = ki.kc.Lkmwhere:"kc" is a coefficient determined by the number of downconductors per ESEAT:kc = 1 for one down conductor, kc = 0.75 for two down conductors, kc = 0.6 for three conductors, kc = 0.41 for four ormore conductors." ki " is determined by the required protection level:ki = 0.08 for protection level 1 (high protection), for veryexposed or strategic buildingski = 0.06 for protection level 2 (reinforced protection, exposedbuilding)ki = 0.04 for protection level 3 & 4 (standard protection)"km" is related to the material situated between the twoloop ends:km : 1 for airkm = 0.5 for a solid material other than metal"L" is the length between the point at which proximity ismeasured and the point at which the metallic network isearthed or the nearest equipotential bonding point.S1L1L2S2air conditioningearthingbarExampleAn ESEAT with two down conductors protects a 20 m highbuilding with protection level I.– Question 1 : Should an air conditioning extractor locatedon the roof be interconnected if 3 m away from the downconductor? Length L1 = 25 m.Answer 1 : S1 = 0.08 x 0.75 x 25 / 1 = 1.5 mSince the distance (3 m) between the conductor and the airconditioningsystem is greater than the separation distance(1.5 meters), there is no need to interconnect this extractor.– Question 2 : Should the computer located in the building 3m away from the down conductor be interconnected withthe conductor, where L2 = 10 m?Answer 2 : S2 = 0.08 x 0.75 x 10 / 0.5 = 1.2 mSince the distance between the computer and the downconductor (3 m) is greater than the separation distance(1.2 m), there is no need to interconnect this computer.A tool is available that can be used to quickly calculate theseparation distances.20 | ABB OPR lightning protection systemsEquipotential bondingEquipotential bonding of external metallic networksThe equipotential bonding of external metallic networks is anintegral part of the outdoor lightning protection installation justlike the down conductors and their earths.All conductive metallic networks located at a distance of lessthan s (separation distance) from a conductor should beconnected to the conductor by a conductive material with alike cross-section.The aerial masts and small posts supporting electrical powerlines should be connected to the conductor via a mastarrester. Earthing systems embedded in walls should beconnected to the conductor if terminal connections have beenprovided.Equipotential bonding of internal metallic networksThe equipotential bonding of internal metallic networks is anintegral part of the indoor lightning protection installation.All conductive metallic networks in the structure (steelframeworks, ducts, sheathing, electrical raceways or telecommunicationcable trays, etc.) should be connected to theconductor. This is done by using a conductive material witha cross-section of at least 6 mm² for copper or 16 mm² forsteel to connect to equipotential bonding bars installed insidethe structure and connected in turn to the closest point of theearthing circuit.Unscreened telecommunication or electrical conductorsshould be bonded to the lightning protection system via surgearresters.Equipotential bonding of earthsThis is done by using a conductive material with across-section of at least 16 mm² for copper or 50 mm²for steel to connect bonding bar to earth termination system.interconnection withbuilding loop112233telephone line protectionlow voltage power supplyprotectionIT system protection44TV protectionESEAT OPRABB OPR lightning protection systems | 21Earth termination systemsOverviewEach down conductor in a lightning protection system must beconnected to an earth termination system which fulfils four conditions:– The earth termination resistance valueInternational standards stipulate an earth termination resistancevalue of less than 10 ohms.This value should be measured on the earth connection isolatedfrom any other conductive component.If the resistance value of 10 ohms cannot be achieved, the earthtermination is nonetheless considered compliant if it is made up ofat least 160 m (protection level 1) or 100 m (protection level 2, 3& 4) of conductors or electrodes, each section measuring no morethan 20 m.– Current carrying capacityThis is an often overlooked but essential aspect of lightningconduction. To minimise the earthing system impedance value, a parallel configuration of three electrodes is strongly recommendedinstead of just one excessively long electrode.– Equipotential bondingStandards require the equipotential bonding of lightningearth termination systems with the existing earthing systems.This must be done using 16 mm² (copper) or 50 mm² (steel)minimum cross section conductor.– Distance from buried utilitiesEarth termination should be at least 2 m (if soil resistivity is over500 ohms/m 5 m) distant from any buried metal pipe or electricalconduit, not connected to the main equipotential bonding of thestructure.Inspection earth pitThe connection parts of an earth termination system (duck's footconnector, earth rod, test joint) can be accessed in an inspection earthpit.Lightning air terminalsDucks foot connectorThe minimum earth termination system is made up of 25 m of30 x 2 mm tin-plated copper strip, split into 3 strands buried in3 trenches at a depth of 60 to 80 cm dug in a fan shape like a duck'sfoot: one end of the longest strand is connected to the test joint, thetwo other strands being linked to a special connection known as aduck foot's connector.Earth rodsWhen the site topography does not lend itself to the installation of aduck's foot as described above, an earth termination system can bedeveloped using at least 3 copper earth rods each with a minimumlength of 2 m, buried vertically in the ground; the rods should bespaced at intervals of about 2 m and at a mandatory distance of 1 mto 1.5 m from the foundations.protectionat30 x 2 mm down conductor6 to 9 m depending on soilresistance1 m from wall depth60 to 80 cm8 to 12 mstainlesssteel clampNB: the earth termination is covered by a red or orange warning gridDUCK'S FOOT EARTHTERMINATION SYSTEMduck'sfootconnectorDuck's foot earth termination systemIt is recommended to cover the earth termination system with a red or orange warningplastic mesh.protectionat30 x 2 mm strip2 m1 m from wall depth60 to 80 cmstainless steelclampNB: the earth termination is covered by a red or orange warning grid 2 m rodearth rod clampROD TRIANGLE EARTHTERMINATION SYSTEMRod triangle earth termination systemIt is recommended to cover the earth termination system with a red or orange warningplastic mesh.DUCK'S FOOT EARTH TERMINATIONSYSTEM WITH EARTH RODSprotectionat30 x 2 mm strip8 to 12 mdepth 6 to 9 m 60 to 80 cmduck'sfootconnectorstainlesssteel clampNB: the earth termination is covered by a red or orange warning gridrodearth rodclamp1 m from wallDuck's foot earth termination system with earth rodsIt is recommended to cover the earth termination system with a red or orange warningplastic mesh.22 | ABB OPR lightning protection systemsEarth termination systemsCombinedIf the soil type is not altogether suitable for a duck's foot connector, a combination of duck's foot and earth rods will significantlyenhance protection (better earth resistance). In this case, the endof each duck foot connector strand is connected to an earth rod.Meshed conductorsDuck's foot connectorThe earth connection is made up of 3 conductors each 3 mminimum in length, buried horizontally at a depth of 60 to 80 cm.One of the strips is connected to one end of the test joint; theother two splay out at an angle of 45° on either side of this centralstrand and are coupled to it with a special connector known as aduck's foot connector. The resistance value must be less than 10ohms. If the resistance value of 10 ohms cannot be achieved, theearth termination is nonetheless considered compliant if it is madeup of at least 160 m of electrode in level 1, 100 m in level 2 and10 m in level 3 & 4.Earth rodsThe earth connection is made up of 2 spiked vertical rods at least2 m in length, connected to each other and to the down conductor, and at least 2 m from each other. The rods should be 1 m to1.5 m from the foundations. The earth termination systems in abuilding should be connected together with a conductor with thesame cross-section and of the same type as the down conductors.Where there is an existing entrenched earth protection loopin the foundations for the building's 2 m flat electrical installations, there is no need to create a new loop: the earth terminations cansimply 0.6 m be interconnected by a tin-plated 30 x 2 mm copperstrip. The resistance value must be less than 10 ohms. If the resistancevalue of 10 ohms cannot be achieved, the earth terminationis nonetheless considered compliant if it is made up of at least160 m (80 m if vertical rods) of electrode in level 1, 100 m (50 m ifvertical rods) in level 2 and 10 m (5 m if vertical rods) in level 3 & 4.Earthing system equipotential bondingWhen the protected building or area has an existing earth terminationsystem for the electrical installations, the lightning earthtermination systems should be connected to it.This interconnection should be made to the earthing circuit at theclosest point to the down conductor.When this is impossible in an existing building, the interconnectionshould be made to the earth plate. In this case, the interconnectingconductor should be constructed such that no currents areinduced in nearby equipment cables.In all cases, the interconnection should include a device that canbe disconnected to enable measurements of the resistance of thelightning earth termination system.This device can be made up of either an interconnection box forequipotential bonding fixed to the main wall of the building, or anequipotential bonding bar located in an inspection earth pit.Duck's foot system for a meshed cageIt is recommended to cover the earth termination system with a red or orange warningplastic mesh.protectionat30 x 2 mm strip3 m1 m from wall depth60 to 80 cm4 mstainlesssteel clampNB: the earth termination is covered by a red or orange warning gridDUCK'S FOOT SYSTEMFOR A MESHED CAGEduck'sfootconnector2 m0.6 m2 mtestjointprotectionat2 rodsD: down conductor of a lightning air terminalB: entrenched building loopP: lightning conductor earth termination systemtestjointdisconnectableconnectionDPBABB OPR lightning protection systems | 23Inspection ESEAT maintenanceThe current standards NF C 17-102 September 2011 editionrecommends regular, periodical inspections of the lightningprotection system.The following schedules are recommended:Protection level Visual inspection(year)Complete inspection(year)Critical system completeinspection (year)I and II 1 2 1III and IV 2 4 1Note: Critical systems shall be defined by laws or end users.A lightning protection system should also be inspected wheneverthe protection structure is modified, repaired or when thestructure has been struck by lightning.Lightning strikes can be recorded by a lightning strike counterinstalled on one of the down conductors.ESEAT maintenance kit, a unique solutionWith its experience of ESEAT development and specialtesting processes, ABB offers a simple and complete solution:a telescopic 8 m pole supplied with a portable test case toenable simple in situ inspections.The device can be used without dismantling the ESEAT.The following aspects of an ESE System installationshould be inspected (see NF C 17-102 September 2011edition pagraph 8)A visual inspection should be performed to make sure that:– no damage related to lightning has been noted– integrity of ESE System has not been modified– no extension or modification of the protected structureneeds the installation of additional lightning protectionmeasures– the electrical continuity of visible conductors is correct– all component fasteners and mechanical protectors are ingood condition– no parts have been weakened by corrosion– the separation distance is respected and there are enoughequipotential bondings and their condition is correct– SPD end of life indicator is correct– maintenance operations results are checked and recordedComplete verification includes visual verification and thefollowing measurements to check:– the electrical continuity of hidden conductors– the earth termination system resistance values (anyvariation with regards to initial values > 50 % should beanalysed)– properly working of ESEAT according to manufacturerprocedure.NOTE: High frequency earth system measurement is feasible during installation or inmaintenance operation in order to check the coherence between the needs and theinstalled earth system.The findings of each scheduled inspection should be recordedin a detailed report stating the required corrective measures.Any faults identified in a scheduled inspection should becorrected as soon as possible in order to maintain optimallightning protection.Initial verification should be performed once the ESE systeminstallation is completed in order to make sure that it complieswith the NF C 17-102 standard requirements.24 | ABB OPR lightning protection systemsLightning air terminal rangeESEAT typical installation on masonry buildingOPR lightning conductorp.26Coupling accessoriesp.36Hooks p.37Test joint p.39Duck foot connectorp.41Lightning strokecounter and recorderp.43Extension mast p.31Conductor supportingstud p.37Ruberalu bracketsp.37Antenna mastarrester p.43Boltedbrackets p.33Protecting flatp.39Equipotential boxp.39Type 1 surge protective devicehighly recommendedABB OPR lightning protection systems | 25Lightning air terminal rangeESEAT typical installation on metal claddingOPR lightningconductor p.26Threaded basesp.35Test joint p.39Interconnection boxp.39Lightning strokecounter p.43Stainless steel clipp.37Protecting flatp.39Water deflecting conesp.35WaterproofStainless steel clipp.37Type 1 surge protective devicehighly recommended26 | ABB OPR lightning protection systemsLightning air terminal range - Early Streamer EmissionOPR, the high pulse voltage, initiation advance lightningair terminalABB continues to innovate, and has developed a new generationof lightning devices.

Validated in the laboratory, this gain in time relative tothe simple rod provides additional essential protection.Complete autonomyDuring a storm the ambient electric field may rise to between10 to 20 kV/m. As soon as the field exceeds a thresholdrepresenting the minimum risk of a lightning strike, the OPRlightning terminal is activated. It draws its energy from theambient electric field the energy required to generate highvoltage pulses, creating and propagating an upward leader.No other power sources are required, and no radioactivecomponents are used.Upward leaders Return arc Meeting pointA B C DOPR Upward leaders Meeting pointA B C DABB OPR lightning protection systems | 27RodCheck system: visual strike indicatorThe aim of the RodCheck system is to give visual information on the intensity of the lightning current caughtby the OPR even from a long distance.We need to keep in mind that the lightning rod is a security device that permits to limit risk and thereforecontributes to the safety of the people. Indeed a lightning impact may lead to explosion, to fire and consequentlybe a risk for the people within the structure.As for any security device, it is important to figure out directly its degree of aging, which is linked to the lightningstrike current to which it has been subjected.On many sites lightning rods are usually equipped with counters that detect the flow of current without necessarilygiving information about its intensity.Only a digital counter could give such characteristics, but it would undoubtedly increase the price of theoverall installation.On the other hand, the new edition of the NF C 17-102 also states that from January 2009 it has been compulsoryto have two down conductors per ESEAT. Therefore, as the counters are usually placed only on oneof the two down conductors, they don't record the entire value of the current.The RodCheck system has been developed so as to solve this specific security issue and it provides anestimate of the intensity of the lightning strike at first glance.Thanks to the new RodCheck technology, the OPR considerably reinforces and improves the security of sitesand people and provides the right answer to a perfectly justified question: "Has the lightning rod been deeplyhit and is it necessary to check the installation?"This visual indicator is made of a UV resistant EPDM shell, mounted directly on the OPR external spark gap.RodCheck has not beenhit by a lightning strokeRodCheck after lightningstroke of few kARodCheck after severalstrokes or one of more than40 kALightning air terminal rangeEarly Streamer Emission Air Terminal - ESEAT1 2 3In the examples 2 and 3 we recommend performing a test of the OPR's electronics and afterwards the redring may be put back in the initial position (example 1).As long as there is no indication of strike it is not necessary to test the generator. But on the other hand, westrongly recommend a complete check of the lighting rod OPR, including the check of its internal electronicsystem in case of a lightning impact. An 8 m high pole connected to a test case is needed to carry out thetest of the generator.28 | ABB OPR lightning protection systemsLightning air terminal rangeEarly Streamer Emission Air Terminal - ESEATTypical applicationsIndustrial sites, buildings, warehouses, where a large protection area is needed.Ordering detailsOPR∆T Description Type Order code Ean code Pkg(pcs)Weight(1 pce)µs kg30 OPR 30 IMH3000 2CTB899800R7000 3660308514172 1 2.40045 OPR 45 IMH4500 2CTB899800R7500 3660308514706 1 2.40060 OPR 60 IMH6000 2CTB899800R7100 3660308514189 1 2.400Mast to be ordered separately.Maximum operating temperature: 120 °C.OPR radius of protectionLevel of protection I (r = 20 m) II (r = 30 m) III (r = 45 m) IV (r = 60 m)Type OPR 30 OPR 45 OPR 60 OPR 30 OPR 45 OPR 60 OPR 30 OPR 45 OPR 60 OPR 30 OPR 45 OPR 60h (m) Radius of protection Rp (m)2 19 25 31 22 28 35 25 32 39 28 36 433 29 38 47 33 42 52 38 48 58 43 57 644 38 51 63 44 57 69 51 65 78 57 72 855 48 63 79 55 71 86 63 81 97 71 89 1076 48 63 79 55 71 87 64 81 97 72 90 1078 49 64 79 56 72 87 65 82 98 73 91 10810 49 64 79 57 72 88 66 83 99 75 92 10915 50 65 80 58 73 89 69 85 101 78 95 11120 50 65 80 59 74 89 71 86 102 81 97 11345 43 65 76 58 75 89 75 90 105 89 104 11950 40 65 74 57 75 88 75 90 105 89 104 12055 36 65 72 55 75 86 74 90 105 90 105 12060 30 65 69 52 75 85 73 90 104 90 105 120Note: the optimized radius of protection is reached when placing the ESE lightning conductor at 5 m above the highest point of the structure to protect.

This typeof cloud is very extensive, both horizontally (about 10 km indiameter) and vertically (up to 15 km). Its highly characteristicshape is often compared with the profile of an anvil of whichit displays the upper and lower horizontal planes. The existenceof extreme temperature gradients in a cumulonimbus(the temperature can drop to -65 °C at the top) generatesvery rapid ascending air currents, and results in the electricalenergisation of the water particles.In a typical storm cloud, the upper part, consisting of icecrystals, is normally positively charged, whilst the lower part, consisting of water droplets, is negatively charged. Consequently, the lower part of the cloud causes the developmentof electrically opposite charges (i.e. positive over the part ofthe ground nearby).Thus the cumulonimbus formation constitutes a sort of hugeplate /ground capacitor whose median distance can oftenreach 1 to 2 km. The atmospheric electrical field on theground, about 600 V/m in fine weather is reversed and canreach an absolute value of 15 to 20 kV/m when a grounddischarge is imminent (the lightning stroke).Before and during the appearance of the lightning stroke, discharges can be seen both within the cloud and betweenclouds.LightningAccording to the direction in which the electrical dischargedevelops (downward or upward), and the polarity of thecharges it develops (negative or positive), four classes ofcloud-to-ground lightning stroke can be distinguished. Inpractice, lightning strokes of the descending and negativetype are by far the most frequent: it is estimated that on plainsand in our temperate zones, they account for 96 % of allcloud / ground discharges.Mechanism of a lightning strokeIt is impossible to discern the individual phases of the lightningstroke by simple visual observation. This can only bedone with high-speed cameras. Most lightning bolts exhibitthe following phenomena: a leader leaves a point in thecloud and travels about 50 m at a very high speed of around50 000 km/s. A second leader then leaves the same point, follows the previous path at comparable speed, goes beyondthe final point of the first leader by an approximately identicaldistance, then disappears in turn.The process is repeated until the tip of the last leader reachesa point a few dozen metres, or even just a few metres aboveground level.The ascending jets then converge, producing a return strokefrom the ground towards the cloud (the upward streamer) duringwhich the electric current circulates: The convergence ofthese two phenomena produces the main discharge, whichmay be followed by a series of secondary discharges, passingunbroken along the channel ionised by the main discharge.In an average negative lightning stroke, the maximum currentis around 35 000 A.----------- - - -+++ ++++ + ++++++++++ + + + + + + + + + + + + + + + + + + +ABB OPR lightning protection systems | 3Lightning protection technologiesThe effects of lightningThe effects of lightning are those of a high-strength impulsecurrent that propagates initially in a gaseous environment (theatmosphere), and then in a solid, more or less conductivemedium (the ground):– visual effects (flash): caused by the Townsend avalanchemechanism– acoustic effects: caused by the propagation of a shockwave (rise in pressure) originating in the discharge path;this effect is perceptible up to a range of around 10 km– thermal effect: heat generated by the Joule effect in theionised channel– electrodynamic effects: these are the mechanical forces appliedto the conductors placed in a magnetic field createdby the high voltage circulation. They may result in deformations– electrochemical effects: these relatively minor effects areconveyed in the form of electrolytic decomposition throughthe application of Faraday's law– induction effects: in a variable electroma-gnetic field, everyconductor harnesses induced current– effects on a living being (human or animal): the passage ofa transient current of a certain r.m.s value is sufficient toincur risks of electrocution by heart attack or respiratoryfailure, together with the risk of burns.Lightning causes two major types of accidents:– accidents caused by a direct stroke when the lightningstrikes a building or a specific zone. This can cause considerabledamage, usually by fire. Protection against thisdanger is provided by lightning air terminal systems– accidents caused indirectly, as when the lightning strikes orcauses power surges in power cables or transmission links.Hence the need to protect with SPD the equipment at riskagainst the surge voltage and indirect currents generated.Protection against direct lightning strokeTo protect a structure against lightning strokes, a preferredimpact point is selected to protect the surrounding structureand conduct the flow of the electric current towards theground, with minimal impedance on the path followed bythe lightning. Four types of protection systems meet theserequirements.Protection systems StandardsEarly streamer emission air terminal - France: NF C 17-102 (September 2011 edition)- Argentina: IRAM 2426- Spain: UNE 21186- Macedonia: MKS N.B4 810- Portugal: NP 4426- Romania: I-20- Slovakia: STN 34 1391- Serbia: JUS N.B4.810Single rods air terminals IEC 62 305-3Meshed cages IEC 62 305-3Stretched wires IEC 62 305-34 | ABB OPR lightning protection systemsLightning protection system with early streamer emissionair terminal (ESEAT)These state-of-the-art technologies have been designed onthe basis of a series of patents registered jointly by HELITAand the French National Scientific Research Centre (CNRS).The OPR is equipped with an electronic device which is highpulse voltage of known and controlled frequency and amplitudeenabling the early formation of the upward leader which isthen continuously propagated towards the downward leader.This anticipation in the upward leader formation is essentialwith regard to the last scientific knowledge on the lightningattachment that acknowledge the fact that this one resultsfrom an upward leader competition. Today the upward leadercompetition is internationally recognized thanks to high speedcameras pictures of this phenomenon of attachment and to itsdigital simulation.The OPR draws its energy from the ambient electrical fieldduring the storm. After capturing the lightning stroke, the OPRdirects it towards the down conductors to the ground where itis dissipated.Triggering time of an ESEAT1 2Lightning protection technologiesABB OPR lightning protection systems | 5The early streamer emission (ESE) conceptDuring a storm, when the propagation field conditions arefavourable, the OPR first generates an upward leader. Thisleader from the OPR tip propagates towards the downwardleader from the cloud at an average speed of 1 m/µs.The triggering time ∆T (µs) is defined as the mean gain atthe sparkover instant (continuous propagation of the upwardleader) obtained with an ESE air terminal compared with asingle rod air terminal exposed to the same conditions. ∆T ismeasured in the high-voltage laboratory, all tests are definedin appendix C of the French standard NF C 17-102.The triggering time instance gain ∆T is associated with atriggering time distance gain ∆L.∆L = v. ∆T, where:– ∆L (m): gain in lead distance or sparkover distance– v (m/µs): average speed of the downward tracer (1 m/µs).– ∆T (µs): gain in sparkover time of the upward leadermeasured in laboratory conditions.OPR air terminals are especially effective for the protectionof classified industrial sites, administrative or public buildings, historical monuments and open-air sites such as sportsgrounds.Lightning protection technologies6 | ABB OPR lightning protection systemsLightning protection technologiesLightning protection system with meshed cagesThis principle consists of dividing up and more easily dissipating thelightning current by a network of conductors and earths.A meshed cage installation has multiple down conductors andconsequently provides very effective protection for buildingsthat house equipment sensitive to electromagnetic disturbance.This is because the lightning current is divided among the downconductors and the low current circulating in the mesh creates verylittle disturbance by induction.A meshed cage installation is made up of:– devices to capture the atmospheric discharges consisting ofstrike points– roof conductors– down conductors– protection measures against injuries to leaving being due totouch and step voltages (e.g. warning notice)– an equipotential bonding between each earth and the generalearthing circuit of the structure; this one must be disconnectable.Installation conditionsLightning Protection System with an ESEAT is made of:– an Early Streamer Emission Air Terminal and its extension mast– two down conductors, or in case of several ESEAT oneconductor per ESEAT– a connecting link or test joint for each down conductor toenabling the earth resistance to be verified– a protecting flat to protect the down conductor for the last twometers above ground level– an earth designed to dissipate the lightning currents at thebottom of each down conductor– an equipotential bonding between each earth and the generalearthing circuit of the structure; this one must be disconnectable– protection measures against injuries to leaving being due totouch and step voltages (e.g. warning notice).Lightning protection system with single rod air terminalBy protruding upwards from the building, they are likely to triggerthe release of ascending streamers and thus be selected asimpact points by lightning strokes occurring within the vicinity of thestructure.This type of protection is especially recommended for radio stationsand antenna masts when the area requiring protection is relativelysmall.A single rod air terminal protection is made up of:– a rod lightning air terminal and its extension mast– two down conductors– a connection link or test joint on each down conductor to checkthe conductor earth resistance– a protecting flat to protect the down conductor for the last twometers above ground level– an equipotential bonding between each earth and the generalearthing circuit of the structure; this one must be disconnectable– protection measures against injuries to leaving being due totouch and step voltages (eg warning notice).ABB OPR lightning protection systems | 7Lightning protection technologiesStretched wiresThis system is composed of one or several conductor wiresstretched above the protected installation. The protection area isdetermined by applying the electro-geometrical model.The conductors must be earthed at each end.A stretched wire installation requires a thorough preliminary studyto consider issues such as mechanical strength, the type ofinstallation, and the insulation distances.This technology is used to protect ammunition depots and as ageneral rule in circumstances where the site cannot be protectedby using a building structure to support the conductors thatconvey the lightning currents to the earth.Protection against indirect lightning stroke effectsWhen lightning strikes cables and transmission lines (H.F. coaxialcables, telecommunication lines, power cables), a voltage surgeis propagated and may reach equipment in the surrounding. Thisvoltage surge can also be generated by induction due to theelectromagnetic radiation of the lightning flash.This can have many consequences: premature componentageing, destruction of printed circuit boards or component plating, equipment failure, data loss, programs hanging, line damage, etc. This is why you need to use Surge Protective Devices toprotect equipment liable to be affected by lightning strikes.The use of Surge Protective Devices is highly recommendedwhen the building is fitted with an external lightning protection. Atype 1 SPD is highly recommended or even mandatory in somecountries. A good protection is made in step with one type 1 fittedin the MDB when the SDB are fitted with type 2 SPDs.Early Streamer EmissionAir TerminalMDBSDB - SubDistribution BoardSDBTelephone inputMainpower inputMDB - MainDistribution BoardTelecomboardEquipotential bonding of metal partsDuring a lightning stroke or even as a result of indirect effects, equipotential bonding defects can, by differences in potential, generate sparkover causing risk for human being or fire into thestructure.This is why it is an essential part of effective lightning protection toensure that a site's equipotential bonding is effective and in goodcondition.The necessity of an electrical insulation between the air terminationor the down-conductor and the structural metal parts, themetal installations and the internal systems can be achieved byproviding a separation distance "s" between the parts. 8 | ABB OPR lightning protection systemsLightning protection risk analysisRisk analysisAll lightning protection standards recommend a preliminarylightning risk analysis in three parts:– lightning risk evaluation– protection level selection– protection device definition.We have developed a software based on the calculations ofthe IEC 62305-2 or NF C 17-102 (appendix A) in order to giveyou an easy and accurate solution regarding the risk analysisof any installation you wish to protect.Lightning flash density map (flashes per km² per year)Protection device definitionIt is advisable to take into account the technical and architecturalconstraints when configuring the different components ofthe protection device.To facilitate your preliminary studies, we will provide a questionnairein which the minimum required information can beentered, and a calculation software package. 2 < Ng < 8 8 < Ng < 18ABB OPR lightning protection systems | 9Lightning protection technical studyOPR Designer softwareABB is happy to provide you with a complete new software in the field of lightningprotection.With a very simple approach you can create your technical study in one click!You can either draw, import file (AutoCAD, pictures…)and from that point get a complete bill of material(air terminals, down conductors, fixing accessoriesand earthing system), the positioning of the lightningprotection system on the structure.The solution is given in a complete pdf file that includes :– protected areas– lightning air terminals positioning– complete bill of material– detailed bill of material per building– catalogue pages for each component– test certificatesThis software is so far available in English, French, Spanish, Russian and Lithuanian version.You may download OPR designer at the following address :http://www.web-emedia.com/opr/10 | ABB OPR lightning protection systemsProcedure for measuring the Early Streamer Emission of an ESEair terminal according to standard NF C 17-102 appendix CThis test procedure consists in evaluating the triggering timeof an Early Streamer Emission (ESEAT) compared with thereference Single Rod Air Terminal (SRAT) in high voltage laboratoryconditions. 50 shocks are applied to the single rod air terminalin the first configuration, then to the early streamer emission airterminal in a second configuration.Simulation of natural conditionsNatural conditions can be simulated in a laboratory by superimposinga permanent field and an impulse field associated with a plate /ground platform area (H). The tested lightning air terminal is placedon the ground, beneath the centre of this platform. In the experiment, the height H = 6 m, and the lightning air terminal heighth = 1.5 m.Electrical conditionsThe permanent field caused by the charge distribution in thecloud is represented by a negative DC voltage of -20 to -25 kV/m(simulating a negative field of around -20 to -25 kV/m) applied tothe upper plate. The impulse field caused by the approach of thedownload leader is simulated with a negative polarity wave appliedto the platform. The rise time of the wave Tm is 650 µs. The wavegradient, at the significant points is around 109 V/m/s.Geometrical conditionsThe volume used for the experiment must be large enough to allowthe ascending discharge to develop freely:– distance d between upper platform and tip ≥ 1 m– upper plate diameter ≥ distance from upper plate to ground.The lightning air terminal are tested in sequence in strictly identicalgeometrical conditions same height, same location, same distancebetween tip and upper platform.ESE air terminals triggering time calculationGeneral conditions– number of shocks: around 50 per configuration (sufficient for anaccurate analysis of the leader /Leader transition)– interval between shocks: the same for each configuration equalto 2 min.Recording– triggering time (TB): obtained directly by reading the data fromthe diagnostic equipment.

For this purpose, weare using high speed cameras, lightning current recorders aswell as field and light recorders.Another in situ test runs at the Taoulet station 2300 m to verifythat theoretical values announced are also validated in realconditions.A constant partnership with scientists permits to follow thesein situs sites and lead to fundamental research on lighting.

Ideally, these vulnerable pointsshould be selected for lightning air terminal installation.The lightning air terminal may be raised by an extension mast.Our stainless steel interlocking extension masts can reachan overall height of 8.50 or 11 m including the lightning airterminal height. They have been specially designed to obviatethe need for guying. However, if guying is essential (e.g. whenthe conductor is fixed with a flat support on the roof waterproofing, or is exposed to particularly strong winds), the guysshould be made of Ø 5.6 fibre glass. When metal cables areused for guying, the lower anchoring points should be interconnectedwith the down conductor by a conductive materialof the same type. We offer a range of fixtures adapted to mostrequirements.Installation specifications are detailed in the individual productdata sheets.If several lightning air terminals (ESEAT or SRAT) are used inthe outside installation on the same structure, they should beconnected by a conductor, except when this has to pass anobstacle of more than 40 cm in height.D ≤ 40 cm: connect ESEATsD ≥ 40 cm: do not connect air terminalsWhen protecting open-air sites such as sports grounds, golfcourses, swimming pools, and camping sites, ESEATs areinstalled on special supports such as lighting masts, pylons, or any other nearby structures from which the conductor cancover the area to be protected.Our software OPR Designer is able to design a completelightning protection system with all installations details, listingof material, protections areas layout, tests certificates within acomplete technical document that is available for the client inpdf format.d ≤ 40 cm d ≤ 40 cm d ≤ 40 cmInterconnection rule when several ESEAT on the same roofABB OPR lightning protection systems | 15Lightning capture devicesSpecial casesAntennasBy agreement with the user of the antenna, the device canbe mounted on the antenna mast, provided that allowance ismade for a number of factors notably:– the lightning air terminal tip must culminate at least 2 mabove the antenna– the aerial coaxial cable is routed inside the antenna mast– the common supporting mast will no need guying– the connection to the down conductor will be made using aclamp fixed to the foot of the mast.This process, widely used today, offers three advantages:– technical (it earths the aerial itself)– visual (there is only one mast)– cost.To be noted that an ESEAT electronic generator cannot beused in an atmosphere where the temperature is greater than120°.Industrial chimneyESE air terminal:– the lightning air terminal should be mounted on an offsetmast (2CTH0HRI3501) as far as possible from smoke andcorrosive vapours– the mast should be fixed to 2 points as shown in the diagram.To be noted that an ESEAT electronic generator cannot beused in an atmosphere where the temperature is greater than120°.Single rod air terminal:The lightning air terminals (1 or 2 m) should be mounted onstainless steel supports (2CTH0HPS2630) to enable mountingat a 30° angle. They will be interconnected by a belt conductorpositioned 50 cm from the summit of the chimney.When using 1 m air terminal at least two points should beused and placed at intervals of no more than 2 m around theperimeter.When using strike points of at least 2 m in height, the numberof points should be calculated to cover the protection radius.SteepleThe lightning air terminal have been designed to carry roofornaments (rooster, weathervane, cardinal points, etc.).The down conductor is then fixed below the ornaments.2 mminimumESEATØ 35 mm stainless steelESEAT mast2CTH070011R0000500 mmantennasteel hoopsdownconductorESEAToffset mastdown conductorwind indicatorroostertightening screwcardinalpointsconnecting clamp750 mmESEAT basedown conductorESEAT16 | ABB OPR lightning protection systemsDown conductorsOverviewDown conductors should preferably be made with tin-platedred copper strips, 30 mm wide and 2 mm thick.Lightning is a high frequency current that flows along theperiphery of the conductors. For a like cross-section, a flatconductor has a greater periphery.An exception to the above rule is buildings with aluminiumcladding on which a copper down conductor might generatean electrolytic coupling phenomenon.Here a 30 x 3 mm aluminium strip should be used or bimetalconnection.In some cases where it is impossible to fix the copper strip, around Ø 8 mm tin-plated copper conductor. In the case wherethere is a need of mechanical movement of the down conductoruse a 30 x 3 mm flexible tin-platted copper braid.PathThe path should be planned to take account of the location ofthe earth termination. The path should be as straight and shortas possible avoiding any sharp bends or upturns. Curvatureradii should be no less than 20 cm. To divert the down conductorlaterally, 30 x 2 mm tin-plated red copper preformedbends should be used.The down conductor path should be chosen to avoid intersectionand to be routed along electrical ducts. Shieldingthe electrical ducts 1 m on each side can be done when it isimpossible to avoid crossing them. However when crossoverscannot be avoided, the conduit should be protected insidemetal sheeting extending by 1 m on either side of the crossover.This metal sheeting should be connected to the downconductor.However, in exceptional cases where an outside downconductor cannot be installed, the conductor may run downthrough a service duct, provided that this is used for no otherpurpose (and subject to agreement with the safety servicesand inspection organizations).When a building is fitted with a metallic external cladding orstone facing or in glass, or in the case of a fixed covering partof the facade, the down conductor can be installed on theconcrete facade or on the main structure, under the cladding.In this case, the conductive parts of the cladding must beconnected to the down conductor at the top and at thebottom.The down conductor, if not a copper one, shall be located atmore than 10 cm behind inflammable material of the outsidecladding if its cross section area if lower than 100 mm². Forcross section area of 100 mm² or greater, there is no need tokeep a distance between the down conductor and theflammable material.A specific calculation of the temperature increase may be performedto validate a different rule.The same requirements apply also to all inflammable materialeven on the roof (e.g. thatched roof).Indoor routingWhen a down conductor cannot be installed outside thestructure, it can be fitted inside on a part or on the full heightof the structure. In this case, the down conductor must beplaced inside a dedicated non flammable and insulating duct.The separation distance shall be calculated also for indoordown conductors in order to be able to determine the necessaryinsulation level of the dedicated duct.The building operator has to be aware of the resultingdifficulties to check and maintain the down conductors, and ofthe resulting risks of over voltages inside the building.Access of people to the specific cable channel should beavoided in stormy periods or measures of protection as peroutdoor down conductors should be fulfilled (see Annex DNF C 17-102 Vers September 2011) including equipotentialbondings of floors with the down conductor.Down-conductor bend shapesLd LdLdLLddL: length of the loop, in metersd: width of the loop, in metersThe risk of any dielectricbreakdown is avoided ifthe condition d>L/20is fulfilled.ABB OPR lightning protection systems | 17Down conductorsParapet wallsWhen the face of the parapet wall is less than or equal to40 cm, an upward section in the down conductor is allowedwith a maximum slope of no more than 45°. For parapet wallswith an upward section of more than 40 cm, space should beallowed or a hole drilled to accommodate a 50 mm minimumdiameter sheath and thereby avoid bypassing. If this is notpossible, supports of the same height as the parapet wallshould be installed to avoid an upturn.ConnectionThe lightning air terminal is connected to the downconductor by a connecting clamp that must be tightly securedon to the mast. The strip will be secured along the extensionmasts by stainless steel clamps. The conductors can beconnected together by coupling strips.FastenersWhatever the supporting medium the down conductor mustbe secured by at least 3 fasteners per linear meter. Insulatorsare used to distance the conductors and prevent contact witheasily flammable material (thatch or wood, for example).The fastener must be appropriate for the structure materialand installed so as not to impair watertightness and allow theconductor thermal extension.Test jointEach down conductor must be fitted with a test joint or connectionlink to enable measurement of the resistance of thelightning earth system alone and the electrical continuity of thedown conductor.The test coupling is usually placed about 2 m above groundlevel to make it accessible for inspection purposes only. To becompliant with standards, the test joint should be identified bythe words "lightning air terminal" and the "earth" symbol.On metal pylons, framework or cladding, the test joint shouldbe placed on the ground in inspection earth pit about 1 m fromthe foot of the metal wall to avoid distorting the resistancemeasurement of the earth connection by inevitably measuringthe electrical resistance on the other metallic networks in thebuilding.Protecting flatBetween the test joint and the ground, the strip is protectedby a 2 m galvanized or stainless steel sheet metal flat fixed by3 clamps supplied with the flat.The protecting flat can be bent to follow the profile of thebuilding.Warning Notice: Protection measures against step andtouch voltagesIn certain conditions, the vicinity of the down-conductors of anESE System, outside the structure, may be hazardous to lifestrip 30 x 2 mmcopper roundø 6 or 8 mm330lead play30 or 4030test jointprotectingathookdown conductorstriplead dowelcopper tape30 x 2 mm3 screw-in stainlesssteel clamps on the2 m of protecting atprotecting ateven if the ESE System has been designed and constructedaccording to the above-mentioned requirements.The hazard is reduced to a tolerable level if one of thefollowing conditions is fulfilled:The probability of persons approaching, or the duration oftheir presence outside the structure and close to the downconductors, is very low. The natural down-conductor systemconsists of typically more than ten columns of the extensivemetal framework of the structure or of several pillars ofinterconnected steel of the structure, with the electricalcontinuity assured;The contact resistance of the surface layer of the soil, within3 m of the down-conductor, is not less than 100 kΩ.NOTE: A layer of insulating material, e.g. asphalt, of 5 cmthickness (or a layer of gravel 15 cm thick) generally reducesthe hazard to a tolerable level. If none of these conditions isfulfilled, protection measures shall be adopted against injury toliving beings due to touch voltages as follows:– insulation of the exposed down-conductor is providedgiving a 100 kV, 1.2/50 μs impulse withstand voltage, e.g. at least 3 mm cross-linked polyethylene– physical restrictions and/or warning notices to minimize theprobability of down-conductors being touched.

The counter is connected inserial on the down conductor.Lightning stroke counter and recorder is used to store dateand time of the impact as well as lightning current values.Meshed conductorsOn roofIs carried on the roof meshes with conductors of which thewidth depends on the level of protection and those ones mustnot be greater than 20 m as follows:It is primarily a closed polygon whose perimeter is adjacentthe periphery of the roof, this polygon is then complete bytransverse conductors to satisfy the condition on the maximumwidth of the meshes. If there is a ridge, the conductormust follow it.Air terminals are placed vertically at the highest and mostvulnerable points on the buildings (roof ridges, salient points, edges, corners, etc.).They are arranged at regular intervals around the periphery ofthe roof as follows:– the distance between two 30 cm air terminals should notexceed 15 m– the distance between two 50 cm air terminals should notexceed 20 m– strike air terminals not located on the outer polygon areconnected to the polygon as follows:- either by a conductor excluding any upturn if the air terminalsis less than 5 m from the polygon- or by two conductors in opposite directions forming atransversal section if the air terminals is located morethan 5 m from the polygon.On wallThe down conductors are placed on the corners and salientfeatures of the building in a layout that should be as symmetricaland regular as possible.The average distance between two adjacent down conductorsdepends on the required protection level.Protection level(IEC 62305-2)Distance between 2 downconductors (IEC 62305-3)Roof mesh size(IEC 62305-3)I 10 m 5 x 5II 10 m 10 x 10III 15 m 15 x 15IV 20 m 20 x 20ABB OPR lightning protection systems | 19Equipotential bondingOverviewWhen lightning current flows through a conductor, differencesin potential appear between the conductor and nearby metallicnetworks (steel framework, pipes, etc.) inside or outsidethe building. Dangerous sparks may be produced betweenthe two ends of the resulting open loop.There are two ways to avoid this problem:a) Establish an interconnection providing an equipotentialbond between the conductor and the metallic networksb) Allow a separation distance between the conductor and themetallic networks.The separation distance is the distance beyond which no dangeroussparks can be produced between the down conductorcarrying the lightning current and nearby metallic networks.Because it is often difficult to guarantee that the lightningprotection system is sufficiently isolated during installation orwill remain so in the event of structural changes, on-site work, etc., equipotential bonding is often preferred.There are, however, some cases in which equipotential bondingis not used (e.g. when there are flammable or explosivepiping net-works). In this case, the down conductors arerouted beyond the separation distance "s".Separation distance calculationS (m) = ki.kc.Lkmwhere:"kc" is a coefficient determined by the number of downconductors per ESEAT:kc = 1 for one down conductor, kc = 0.75 for two down conductors, kc = 0.6 for three conductors, kc = 0.41 for four ormore conductors." ki " is determined by the required protection level:ki = 0.08 for protection level 1 (high protection), for veryexposed or strategic buildingski = 0.06 for protection level 2 (reinforced protection, exposedbuilding)ki = 0.04 for protection level 3 & 4 (standard protection)"km" is related to the material situated between the twoloop ends:km : 1 for airkm = 0.5 for a solid material other than metal"L" is the length between the point at which proximity ismeasured and the point at which the metallic network isearthed or the nearest equipotential bonding point.S1L1L2S2air conditioningearthingbarExampleAn ESEAT with two down conductors protects a 20 m highbuilding with protection level I.– Question 1 : Should an air conditioning extractor locatedon the roof be interconnected if 3 m away from the downconductor? Length L1 = 25 m.Answer 1 : S1 = 0.08 x 0.75 x 25 / 1 = 1.5 mSince the distance (3 m) between the conductor and the airconditioningsystem is greater than the separation distance(1.5 meters), there is no need to interconnect this extractor.– Question 2 : Should the computer located in the building 3m away from the down conductor be interconnected withthe conductor, where L2 = 10 m?Answer 2 : S2 = 0.08 x 0.75 x 10 / 0.5 = 1.2 mSince the distance between the computer and the downconductor (3 m) is greater than the separation distance(1.2 m), there is no need to interconnect this computer.A tool is available that can be used to quickly calculate theseparation distances.20 | ABB OPR lightning protection systemsEquipotential bondingEquipotential bonding of external metallic networksThe equipotential bonding of external metallic networks is anintegral part of the outdoor lightning protection installation justlike the down conductors and their earths.All conductive metallic networks located at a distance of lessthan s (separation distance) from a conductor should beconnected to the conductor by a conductive material with alike cross-section.The aerial masts and small posts supporting electrical powerlines should be connected to the conductor via a mastarrester. Earthing systems embedded in walls should beconnected to the conductor if terminal connections have beenprovided.Equipotential bonding of internal metallic networksThe equipotential bonding of internal metallic networks is anintegral part of the indoor lightning protection installation.All conductive metallic networks in the structure (steelframeworks, ducts, sheathing, electrical raceways or telecommunicationcable trays, etc.) should be connected to theconductor. This is done by using a conductive material witha cross-section of at least 6 mm² for copper or 16 mm² forsteel to connect to equipotential bonding bars installed insidethe structure and connected in turn to the closest point of theearthing circuit.Unscreened telecommunication or electrical conductorsshould be bonded to the lightning protection system via surgearresters.Equipotential bonding of earthsThis is done by using a conductive material with across-section of at least 16 mm² for copper or 50 mm²for steel to connect bonding bar to earth termination system.interconnection withbuilding loop112233telephone line protectionlow voltage power supplyprotectionIT system protection44TV protectionESEAT OPRABB OPR lightning protection systems | 21Earth termination systemsOverviewEach down conductor in a lightning protection system must beconnected to an earth termination system which fulfils four conditions:– The earth termination resistance valueInternational standards stipulate an earth termination resistancevalue of less than 10 ohms.This value should be measured on the earth connection isolatedfrom any other conductive component.If the resistance value of 10 ohms cannot be achieved, the earthtermination is nonetheless considered compliant if it is made up ofat least 160 m (protection level 1) or 100 m (protection level 2, 3& 4) of conductors or electrodes, each section measuring no morethan 20 m.– Current carrying capacityThis is an often overlooked but essential aspect of lightningconduction. To minimise the earthing system impedance value, a parallel configuration of three electrodes is strongly recommendedinstead of just one excessively long electrode.– Equipotential bondingStandards require the equipotential bonding of lightningearth termination systems with the existing earthing systems.This must be done using 16 mm² (copper) or 50 mm² (steel)minimum cross section conductor.– Distance from buried utilitiesEarth termination should be at least 2 m (if soil resistivity is over500 ohms/m 5 m) distant from any buried metal pipe or electricalconduit, not connected to the main equipotential bonding of thestructure.Inspection earth pitThe connection parts of an earth termination system (duck's footconnector, earth rod, test joint) can be accessed in an inspection earthpit.Lightning air terminalsDucks foot connectorThe minimum earth termination system is made up of 25 m of30 x 2 mm tin-plated copper strip, split into 3 strands buried in3 trenches at a depth of 60 to 80 cm dug in a fan shape like a duck'sfoot: one end of the longest strand is connected to the test joint, thetwo other strands being linked to a special connection known as aduck foot's connector.Earth rodsWhen the site topography does not lend itself to the installation of aduck's foot as described above, an earth termination system can bedeveloped using at least 3 copper earth rods each with a minimumlength of 2 m, buried vertically in the ground; the rods should bespaced at intervals of about 2 m and at a mandatory distance of 1 mto 1.5 m from the foundations.protectionat30 x 2 mm down conductor6 to 9 m depending on soilresistance1 m from wall depth60 to 80 cm8 to 12 mstainlesssteel clampNB: the earth termination is covered by a red or orange warning gridDUCK'S FOOT EARTHTERMINATION SYSTEMduck'sfootconnectorDuck's foot earth termination systemIt is recommended to cover the earth termination system with a red or orange warningplastic mesh.protectionat30 x 2 mm strip2 m1 m from wall depth60 to 80 cmstainless steelclampNB: the earth termination is covered by a red or orange warning grid 2 m rodearth rod clampROD TRIANGLE EARTHTERMINATION SYSTEMRod triangle earth termination systemIt is recommended to cover the earth termination system with a red or orange warningplastic mesh.DUCK'S FOOT EARTH TERMINATIONSYSTEM WITH EARTH RODSprotectionat30 x 2 mm strip8 to 12 mdepth 6 to 9 m 60 to 80 cmduck'sfootconnectorstainlesssteel clampNB: the earth termination is covered by a red or orange warning gridrodearth rodclamp1 m from wallDuck's foot earth termination system with earth rodsIt is recommended to cover the earth termination system with a red or orange warningplastic mesh.22 | ABB OPR lightning protection systemsEarth termination systemsCombinedIf the soil type is not altogether suitable for a duck's foot connector, a combination of duck's foot and earth rods will significantlyenhance protection (better earth resistance). In this case, the endof each duck foot connector strand is connected to an earth rod.Meshed conductorsDuck's foot connectorThe earth connection is made up of 3 conductors each 3 mminimum in length, buried horizontally at a depth of 60 to 80 cm.One of the strips is connected to one end of the test joint; theother two splay out at an angle of 45° on either side of this centralstrand and are coupled to it with a special connector known as aduck's foot connector. The resistance value must be less than 10ohms. If the resistance value of 10 ohms cannot be achieved, theearth termination is nonetheless considered compliant if it is madeup of at least 160 m of electrode in level 1, 100 m in level 2 and10 m in level 3 & 4.Earth rodsThe earth connection is made up of 2 spiked vertical rods at least2 m in length, connected to each other and to the down conductor, and at least 2 m from each other. The rods should be 1 m to1.5 m from the foundations. The earth termination systems in abuilding should be connected together with a conductor with thesame cross-section and of the same type as the down conductors.Where there is an existing entrenched earth protection loopin the foundations for the building's 2 m flat electrical installations, there is no need to create a new loop: the earth terminations cansimply 0.6 m be interconnected by a tin-plated 30 x 2 mm copperstrip. The resistance value must be less than 10 ohms. If the resistancevalue of 10 ohms cannot be achieved, the earth terminationis nonetheless considered compliant if it is made up of at least160 m (80 m if vertical rods) of electrode in level 1, 100 m (50 m ifvertical rods) in level 2 and 10 m (5 m if vertical rods) in level 3 & 4.Earthing system equipotential bondingWhen the protected building or area has an existing earth terminationsystem for the electrical installations, the lightning earthtermination systems should be connected to it.This interconnection should be made to the earthing circuit at theclosest point to the down conductor.When this is impossible in an existing building, the interconnectionshould be made to the earth plate. In this case, the interconnectingconductor should be constructed such that no currents areinduced in nearby equipment cables.In all cases, the interconnection should include a device that canbe disconnected to enable measurements of the resistance of thelightning earth termination system.This device can be made up of either an interconnection box forequipotential bonding fixed to the main wall of the building, or anequipotential bonding bar located in an inspection earth pit.Duck's foot system for a meshed cageIt is recommended to cover the earth termination system with a red or orange warningplastic mesh.protectionat30 x 2 mm strip3 m1 m from wall depth60 to 80 cm4 mstainlesssteel clampNB: the earth termination is covered by a red or orange warning gridDUCK'S FOOT SYSTEMFOR A MESHED CAGEduck'sfootconnector2 m0.6 m2 mtestjointprotectionat2 rodsD: down conductor of a lightning air terminalB: entrenched building loopP: lightning conductor earth termination systemtestjointdisconnectableconnectionDPBABB OPR lightning protection systems | 23Inspection ESEAT maintenanceThe current standards NF C 17-102 September 2011 editionrecommends regular, periodical inspections of the lightningprotection system.The following schedules are recommended:Protection level Visual inspection(year)Complete inspection(year)Critical system completeinspection (year)I and II 1 2 1III and IV 2 4 1Note: Critical systems shall be defined by laws or end users.A lightning protection system should also be inspected wheneverthe protection structure is modified, repaired or when thestructure has been struck by lightning.Lightning strikes can be recorded by a lightning strike counterinstalled on one of the down conductors.ESEAT maintenance kit, a unique solutionWith its experience of ESEAT development and specialtesting processes, ABB offers a simple and complete solution:a telescopic 8 m pole supplied with a portable test case toenable simple in situ inspections.The device can be used without dismantling the ESEAT.The following aspects of an ESE System installationshould be inspected (see NF C 17-102 September 2011edition pagraph 8)A visual inspection should be performed to make sure that:– no damage related to lightning has been noted– integrity of ESE System has not been modified– no extension or modification of the protected structureneeds the installation of additional lightning protectionmeasures– the electrical continuity of visible conductors is correct– all component fasteners and mechanical protectors are ingood condition– no parts have been weakened by corrosion– the separation distance is respected and there are enoughequipotential bondings and their condition is correct– SPD end of life indicator is correct– maintenance operations results are checked and recordedComplete verification includes visual verification and thefollowing measurements to check:– the electrical continuity of hidden conductors– the earth termination system resistance values (anyvariation with regards to initial values > 50 % should beanalysed)– properly working of ESEAT according to manufacturerprocedure.NOTE: High frequency earth system measurement is feasible during installation or inmaintenance operation in order to check the coherence between the needs and theinstalled earth system.The findings of each scheduled inspection should be recordedin a detailed report stating the required corrective measures.Any faults identified in a scheduled inspection should becorrected as soon as possible in order to maintain optimallightning protection.Initial verification should be performed once the ESE systeminstallation is completed in order to make sure that it complieswith the NF C 17-102 standard requirements.24 | ABB OPR lightning protection systemsLightning air terminal rangeESEAT typical installation on masonry buildingOPR lightning conductorp.26Coupling accessoriesp.36Hooks p.37Test joint p.39Duck foot connectorp.41Lightning strokecounter and recorderp.43Extension mast p.31Conductor supportingstud p.37Ruberalu bracketsp.37Antenna mastarrester p.43Boltedbrackets p.33Protecting flatp.39Equipotential boxp.39Type 1 surge protective devicehighly recommendedABB OPR lightning protection systems | 25Lightning air terminal rangeESEAT typical installation on metal claddingOPR lightningconductor p.26Threaded basesp.35Test joint p.39Interconnection boxp.39Lightning strokecounter p.43Stainless steel clipp.37Protecting flatp.39Water deflecting conesp.35WaterproofStainless steel clipp.37Type 1 surge protective devicehighly recommended26 | ABB OPR lightning protection systemsLightning air terminal range - Early Streamer EmissionOPR, the high pulse voltage, initiation advance lightningair terminalABB continues to innovate, and has developed a new generationof lightning devices. The new OPR range with increasedinitiation advance performances, represents further progressin terms of protection, operating autonomy and ease of maintenance.These advancements reinforce ABB's position asInternational leader in direct lightning protection with over 200000 installations throughout the world.ABB manufacturing qualityThe enviable reputation of the OPR has been earned throughmaintaining a consistently high quality in manufacture. Beforeleaving the factory, each OPR has been tested for installationbreakdown at high voltage, and subjected to a currenttest that ensures its performance when conducting lightningdischarges. The high voltage output pulses at the OPR arealso examined to verify correct amplitude and frequency. TheOPR is built to withstand the arduous conditions encounteredin service, and its ongoing performance can be monitoredsimply and quickly using the OPR test set.The advantage of initiation advanceThe unique efficiency of the OPR lightning air terminal isbased on a specific initiation advance, well before the naturalformation of an upward leader, the OPR generates a leaderthat rapidly propagates to capture the lightning and direct it toearth. Validated in the laboratory, this gain in time relative tothe simple rod provides additional essential protection.Complete autonomyDuring a storm the ambient electric field may rise to between10 to 20 kV/m. As soon as the field exceeds a thresholdrepresenting the minimum risk of a lightning strike, the OPRlightning terminal is activated. It draws its energy from theambient electric field the energy required to generate highvoltage pulses, creating and propagating an upward leader.No other power sources are required, and no radioactivecomponents are used.Upward leaders Return arc Meeting pointA B C DOPR Upward leaders Meeting pointA B C DABB OPR lightning protection systems | 27RodCheck system: visual strike indicatorThe aim of the RodCheck system is to give visual information on the intensity of the lightning current caughtby the OPR even from a long distance.We need to keep in mind that the lightning rod is a security device that permits to limit risk and thereforecontributes to the safety of the people. Indeed a lightning impact may lead to explosion, to fire and consequentlybe a risk for the people within the structure.As for any security device, it is important to figure out directly its degree of aging, which is linked to the lightningstrike current to which it has been subjected.On many sites lightning rods are usually equipped with counters that detect the flow of current without necessarilygiving information about its intensity.Only a digital counter could give such characteristics, but it would undoubtedly increase the price of theoverall installation.On the other hand, the new edition of the NF C 17-102 also states that from January 2009 it has been compulsoryto have two down conductors per ESEAT. Therefore, as the counters are usually placed only on oneof the two down conductors, they don't record the entire value of the current.The RodCheck system has been developed so as to solve this specific security issue and it provides anestimate of the intensity of the lightning strike at first glance.Thanks to the new RodCheck technology, the OPR considerably reinforces and improves the security of sitesand people and provides the right answer to a perfectly justified question: "Has the lightning rod been deeplyhit and is it necessary to check the installation?"This visual indicator is made of a UV resistant EPDM shell, mounted directly on the OPR external spark gap.RodCheck has not beenhit by a lightning strokeRodCheck after lightningstroke of few kARodCheck after severalstrokes or one of more than40 kALightning air terminal rangeEarly Streamer Emission Air Terminal - ESEAT1 2 3In the examples 2 and 3 we recommend performing a test of the OPR's electronics and afterwards the redring may be put back in the initial position (example 1).As long as there is no indication of strike it is not necessary to test the generator. But on the other hand, westrongly recommend a complete check of the lighting rod OPR, including the check of its internal electronicsystem in case of a lightning impact. An 8 m high pole connected to a test case is needed to carry out thetest of the generator.28 | ABB OPR lightning protection systemsLightning air terminal rangeEarly Streamer Emission Air Terminal - ESEATTypical applicationsIndustrial sites, buildings, warehouses, where a large protection area is needed.Ordering detailsOPR∆T Description Type Order code Ean code Pkg(pcs)Weight(1 pce)µs kg30 OPR 30 IMH3000 2CTB899800R7000 3660308514172 1 2.40045 OPR 45 IMH4500 2CTB899800R7500 3660308514706 1 2.40060 OPR 60 IMH6000 2CTB899800R7100 3660308514189 1 2.400Mast to be ordered separately.Maximum operating temperature: 120 °C.OPR radius of protectionLevel of protection I (r = 20 m) II (r = 30 m) III (r = 45 m) IV (r = 60 m)Type OPR 30 OPR 45 OPR 60 OPR 30 OPR 45 OPR 60 OPR 30 OPR 45 OPR 60 OPR 30 OPR 45 OPR 60h (m) Radius of protection Rp (m)2 19 25 31 22 28 35 25 32 39 28 36 433 29 38 47 33 42 52 38 48 58 43 57 644 38 51 63 44 57 69 51 65 78 57 72 855 48 63 79 55 71 86 63 81 97 71 89 1076 48 63 79 55 71 87 64 81 97 72 90 1078 49 64 79 56 72 87 65 82 98 73 91 10810 49 64 79 57 72 88 66 83 99 75 92 10915 50 65 80 58 73 89 69 85 101 78 95 11120 50 65 80 59 74 89 71 86 102 81 97 11345 43 65 76 58 75 89 75 90 105 89 104 11950 40 65 74 57 75 88 75 90 105 89 104 12055 36 65 72 55 75 86 74 90 105 90 105 12060 30 65 69 52 75 85 73 90 104 90 105 120Note: the optimized radius of protection is reached when placing the ESE lightning conductor at 5 m above the highest point of the structure to protect.

Chemical Earthing in DelhiMAINTENANCE FREE CHEMICAL GEL EARTHING:An earthing system is essential for any electrical installation to avoid the danger. related with fault currents, as established in the various national & international standards, an earthing protects both components and people against dangerous touch voltage.A Low Voltage Earth Termination System aims: To give safety for people by limiting the touch voltage. To safe installations and equipment by providing a low impedance path. To provide the best quality of the signal by minimizing the electromagnetic noise. To fix a reference for voltage for the system equipotentializationA minimum Earth Resistance is essential for obtaining an efficient earthing. Conductors with an accurate section should be used in order to carry the expected current.Apart, they mustbe durable against corrosion. The value of the electrical resistance must be measured, isolatedfrom any other conductive element.Therefore, it is necessary to use power breakers in order to separate the earthing from the restof the installation during the measurements.Other determining factors for designing the Earth Termination System are the following: The resistance should be measured regularly so it is necessary to install an inspectionpit. The soil humidity will reduce the earthing resistance. Earthing enhancing compounds reduce the soil resistivity. Buried electricity and gas installations should be known in order to respect the securitydistances for each case. Buried pipes and water tanks should be known in order to bond them equipotentially withthe earth termination.In low-conductivity soils, enhanced earthing electrodes along with the suitable back fillcompound which is filled with natural minerals should be used in order to obtain a suitable earthresistance.Although most electrical systems have fuses or circuit breakers for protection against a faultcurrent, the human body may be fatally electrocuted by a current of less than one ampere whichis well below the point at which a fuse or breaker will operate. Earthing helps minimize suchhazards from occurring.Earthing product ranges are G.I. Pipe Earth Electrodes, Copper Pipe Earth Electrodes, G.I.Earth Rods, Copper Rod, Copper Bonded Steel Rod, Stainless Steel Rod, Zinc Bonded SteelRod, etc.COPPER EARTHING ELECTRODESN Earthing Electrodes is into the manufacturing of high quality copper earthing electrodessuitable for various sensitive applications.
