This type of cloud is very extensive, both horizontally (about 10 km in diameter) and vertically (up to 15 km). Its highly characteristic shape is often compared with the profile of an anvil of which it displays the upper and lower horizontal planes. The existence of extreme temperature gradients in a cumulonimbus (the temperature can drop to -65 °C at the top) generates very rapid ascending air currents, and results in the electrical energisation of the water particles. In a typical storm cloud, the upper part, consisting of ice crystals, is normally positively charged, whilst the lower part, consisting of water droplets, is negatively charged. Consequently, the lower part of the cloud causes the development of electrically opposite charges (i.e. positive over the part of the ground nearby). Thus the cumulonimbus formation constitutes a sort of huge plate /ground capacitor whose median distance can often reach 1 to 2 km. The atmospheric electrical field on the ground, about 600 V/m in fine weather is reversed and can reach an absolute value of 15 to 20 kV/m when a ground discharge is imminent (the lightning stroke). Before and during the appearance of the lightning stroke, discharges can be seen both within the cloud and between clouds. Lightning According to the direction in which the electrical discharge develops (downward or upward), and the polarity of the charges it develops (negative or positive), four classes of cloud-to-ground lightning stroke can be distinguished. In practice, lightning strokes of the descending and negative type are by far the most frequent: it is estimated that on plains and in our temperate zones, they account for 96 % of all cloud / ground discharges. Mechanism of a lightning stroke It is impossible to discern the individual phases of the lightning stroke by simple visual observation. This can only be done with high-speed cameras. Most lightning bolts exhibit the following phenomena: a leader leaves a point in the cloud and travels about 50 m at a very high speed of around 50 000 km/s. A second leader then leaves the same point, follows the previous path at comparable speed, goes beyond the final point of the first leader by an approximately identical distance, then disappears in turn. The process is repeated until the tip of the last leader reaches a point a few dozen metres, or even just a few metres above ground level. The ascending jets then converge, producing a return stroke from the ground towards the cloud (the upward streamer) during which the electric current circulates: The convergence of these two phenomena produces the main discharge, which may be followed by a series of secondary discharges, passing unbroken along the channel ionised by the main discharge. In an average negative lightning stroke, the maximum current is around 35 000 A. - - - - - - - - - - - - - - + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + ABB OPR lightning protection systems | 3 Lightning protection technologies The effects of lightning The effects of lightning are those of a high-strength impulse current that propagates initially in a gaseous environment (the atmosphere), and then in a solid, more or less conductive medium (the ground): – visual effects (flash): caused by the Townsend avalanche mechanism – acoustic effects: caused by the propagation of a shock wave (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 the ionised channel – electrodynamic effects: these are the mechanical forces applied to the conductors placed in a magnetic field created by the high voltage circulation. They may result in deformations – electrochemical effects: these relatively minor effects are conveyed in the form of electrolytic decomposition through the application of Faraday's law – induction effects: in a variable electroma-gnetic field, every conductor harnesses induced current – effects on a living being (human or animal): the passage of a transient current of a certain r.m.s value is sufficient to incur risks of electrocution by heart attack or respiratory failure, together with the risk of burns. Lightning causes two major types of accidents: – accidents caused by a direct stroke when the lightning strikes a building or a specific zone. This can cause considerable damage, usually by fire. Protection against this danger is provided by lightning air terminal systems – accidents caused indirectly, as when the lightning strikes or causes power surges in power cables or transmission links. Hence the need to protect with SPD the equipment at risk against the surge voltage and indirect currents generated. Protection against direct lightning stroke To protect a structure against lightning strokes, a preferred impact point is selected to protect the surrounding structure and conduct the flow of the electric current towards the ground, with minimal impedance on the path followed by the lightning. Four types of protection systems meet these requirements. Protection systems Standards Early 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.B4.810 Single rods air terminals IEC 62 305-3 Meshed cages IEC 62 305-3 Stretched wires IEC 62 305-3 4 | ABB OPR lightning protection systems Lightning protection system with early streamer emission air terminal (ESEAT) These state-of-the-art technologies have been designed on the basis of a series of patents registered jointly by HELITA and the French National Scientific Research Centre (CNRS). The OPR is equipped with an electronic device which is high pulse voltage of known and controlled frequency and amplitude enabling the early formation of the upward leader which is then continuously propagated towards the downward leader. This anticipation in the upward leader formation is essential with regard to the last scientific knowledge on the lightning attachment that acknowledge the fact that this one results from an upward leader competition. Today the upward leader competition is internationally recognized thanks to high speed cameras pictures of this phenomenon of attachment and to its digital simulation. The OPR draws its energy from the ambient electrical field during the storm. After capturing the lightning stroke, the OPR directs it towards the down conductors to the ground where it is dissipated. Triggering time of an ESEAT 1 2 Lightning protection technologies ABB OPR lightning protection systems | 5 The early streamer emission (ESE) concept During a storm, when the propagation field conditions are favourable, the OPR first generates an upward leader. This leader from the OPR tip propagates towards the downward leader from the cloud at an average speed of 1 m/µs. The triggering time ∆T (µs) is defined as the mean gain at the sparkover instant (continuous propagation of the upward leader) obtained with an ESE air terminal compared with a single rod air terminal exposed to the same conditions. ∆T is measured in the high-voltage laboratory, all tests are defined in appendix C of the French standard NF C 17-102. The triggering time instance gain ∆T is associated with a triggering 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 leader measured in laboratory conditions. OPR air terminals are especially effective for the protection of classified industrial sites, administrative or public buildings, historical monuments and open-air sites such as sports grounds. Lightning protection technologies 6 | ABB OPR lightning protection systems Lightning protection technologies Lightning protection system with meshed cages This principle consists of dividing up and more easily dissipating the lightning current by a network of conductors and earths. A meshed cage installation has multiple down conductors and consequently provides very effective protection for buildings that house equipment sensitive to electromagnetic disturbance. This is because the lightning current is divided among the down conductors and the low current circulating in the mesh creates very little disturbance by induction. A meshed cage installation is made up of: – devices to capture the atmospheric discharges consisting of strike points – roof conductors – down conductors – protection measures against injuries to leaving being due to touch and step voltages (e.g. warning notice) – an equipotential bonding between each earth and the general earthing circuit of the structure; this one must be disconnectable. Installation conditions Lightning 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 one conductor per ESEAT – a connecting link or test joint for each down conductor to enabling the earth resistance to be verified – a protecting flat to protect the down conductor for the last two meters above ground level – an earth designed to dissipate the lightning currents at the bottom of each down conductor – an equipotential bonding between each earth and the general earthing circuit of the structure; this one must be disconnectable – protection measures against injuries to leaving being due to touch and step voltages (e.g. warning notice). Lightning protection system with single rod air terminal By protruding upwards from the building, they are likely to trigger the release of ascending streamers and thus be selected as impact points by lightning strokes occurring within the vicinity of the structure. This type of protection is especially recommended for radio stations and antenna masts when the area requiring protection is relatively small. 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 check the conductor earth resistance – a protecting flat to protect the down conductor for the last two meters above ground level – an equipotential bonding between each earth and the general earthing circuit of the structure; this one must be disconnectable – protection measures against injuries to leaving being due to touch and step voltages (eg warning notice). ABB OPR lightning protection systems | 7 Lightning protection technologies Stretched wires This system is composed of one or several conductor wires stretched above the protected installation. The protection area is determined by applying the electro-geometrical model. The conductors must be earthed at each end. A stretched wire installation requires a thorough preliminary study to consider issues such as mechanical strength, the type of installation, and the insulation distances. This technology is used to protect ammunition depots and as a general rule in circumstances where the site cannot be protected by using a building structure to support the conductors that convey the lightning currents to the earth. Protection against indirect lightning stroke effects When lightning strikes cables and transmission lines (H.F. coaxial cables, telecommunication lines, power cables), a voltage surge is propagated and may reach equipment in the surrounding. This voltage surge can also be generated by induction due to the electromagnetic radiation of the lightning flash. This can have many consequences: premature component ageing, 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 to protect equipment liable to be affected by lightning strikes. The use of Surge Protective Devices is highly recommended when the building is fitted with an external lightning protection. A type 1 SPD is highly recommended or even mandatory in some countries. A good protection is made in step with one type 1 fitted in the MDB when the SDB are fitted with type 2 SPDs. Early Streamer Emission Air Terminal MDB SDB - Sub Distribution Board SDB Telephone input Main power input MDB - Main Distribution Board Telecom board Equipotential bonding of metal parts During 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 the structure. This is why it is an essential part of effective lightning protection to ensure that a site's equipotential bonding is effective and in good condition. The necessity of an electrical insulation between the air termination or the down-conductor and the structural metal parts, the metal installations and the internal systems can be achieved by providing a separation distance "s" between the parts. 8 | ABB OPR lightning protection systems Lightning protection risk analysis Risk analysis All lightning protection standards recommend a preliminary lightning risk analysis in three parts: – lightning risk evaluation – protection level selection – protection device definition. We have developed a software based on the calculations of the IEC 62305-2 or NF C 17-102 (appendix A) in order to give you an easy and accurate solution regarding the risk analysis of any installation you wish to protect. Lightning flash density map (flashes per km² per year) Protection device definition It is advisable to take into account the technical and architectural constraints when configuring the different components of the protection device.

Simulation of natural conditions Natural conditions can be simulated in a laboratory by superimposing a permanent field and an impulse field associated with a plate / ground platform area (H). The tested lightning air terminal is placed on the ground, beneath the centre of this platform. In the experiment, the height H = 6 m, and the lightning air terminal height h = 1.5 m. Electrical conditions The permanent field caused by the charge distribution in the cloud 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 to the upper plate. The impulse field caused by the approach of the download leader is simulated with a negative polarity wave applied to the platform. The rise time of the wave Tm is 650 µs. The wave gradient, at the significant points is around 109 V/m/s. Geometrical conditions The volume used for the experiment must be large enough to allow the 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 identical geometrical conditions same height, same location, same distance between tip and upper platform. ESE air terminals triggering time calculation General conditions – number of shocks: around 50 per configuration (sufficient for an accurate analysis of the leader /Leader transition) – interval between shocks: the same for each configuration equal to 2 min. Recording – triggering time (TB): obtained directly by reading the data from the diagnostic equipment. This data is not characteristic, but it does enable a simple reading to establish whether or not a shock 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 the leader continuous propagation instant – pre-discharge current (coaxial shunt): the resulting curves confirm the previous diagnostic data – space-time development of the discharge (image converter): the image converter pictures provide a further means of analysing the results.

T= TSRAT - TESEAT ABB lightning protection group has unique know-how and experience in this field. Since 1996, we have generated more than 40 000 sparks using this test procedure in the following high voltage laboratories: – SIAME Laboratory - PAU UNIVERSITY (France) – Bazet VHV Laboratory - SEDIVER (France) – Volta HV Laboratory - MERLIN GERIN (France) – L.G.E.Les Renardières - ELECTRICITE DE FRANCE – Bagnères de Bigorre HV Laboratory - LEHTM (France) – Varennes IREQ Laboratory (Canada) – Korea Electrotechnology Research Institute - KERI (Korea) – WHVRI - Wuhan High Voltage Research Institute (China) – Beijing testing center surge protective devices (China). 12 | ABB OPR lightning protection systems Tests and research Objectives ABB Lightning Protection Group has been investing for many years in research into lightning air terminal protection devices, and is constantly striving to enhance the performance of its products. ABB's ongoing in situ research in France and abroad has three main objectives: – to enhance the protection models – to measure in situ the effectiveness of ESEAT, already evaluated in laboratory conditions – to qualify the dimensioning of the equipment in real-life lightning strike conditions. Tests under Laboratory conditions Since 2003 our factory located in Bagnères de Bigorre (France) has a high tech laboratory allowing to test our Surge Protective Devices in 10/350 µs and 8/20 µs wave shapes as well as our direct lightning range with lightning currents up to 100 kA. We also test our lighting rods in a dedicated high voltage laboratory close to our factory allowing normative tests thanks to an up to 3 MV generator. Tests in situs An experimental site devoted to the study of direct lightning impacts to a lightning protection system has been selected at the top of the "Pic du Midi" in the French Pyrenées mountains for its high lightning impact density (30 days of storm per year). The "Pic du Midi", famous astronomical observatory, offers an unique scientific environment for lightning observations in collaboration with astronomers. Purpose of the experiments: – to confirm the triggering time of ESEAT compared to single rod air terminals – to direct the flow of the lightning currents captured by the lightning air terminal to low-voltage surge arresters via an appropriate earthing network – to test the resistance of the equipment to lightning shocks and climatological constraints. ABB OPR lightning protection systems | 13 In situ tests at the Pic du Midi de Bigorre This unique location enables us to test our products in highly severe conditions (high winds, extremely low temperatures) as these tests are running at an altitude of 2880 m. Such tests give us the opportunity to complete our understanding on lightning phenomenon. For this purpose, we are using high speed cameras, lightning current recorders as well as field and light recorders. Another in situ test runs at the Taoulet station 2300 m to verify that theoretical values announced are also validated in real conditions. A constant partnership with scientists permits to follow these in situs sites and lead to fundamental research on lighting. As an application example, a software that determines the weak points 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 sites Because lightning is a randomly occurring natural phenomenon, artificial triggering techniques have been developed to speed up the research process. When lightning conditions are prevalent the triggering technique consists in sending a rocket with a trailing wire in the direction of the storm clouds to cause a lightning strike at the experimental site. The wire may comprise an insulating section in order to generate the largest possible number of lightning strikes for experimental purposes. – Site located at Privat d'Allier in Auvergne, France Keraunic level: 30 Purpose 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: 80 Purpose of the experiments: - to confirm the triggering time gain of the ESE air terminals compared with single rod air terminals - to collect data with a view to improving the protection models. Tests and research 14 | ABB OPR lightning protection systems Lightning capture devices Lightning air terminals Early Streamer Emission Air Terminals (ESEAT) or Single Rod Air Terminals (SRAT). As a general rule, the lightning air terminal should culminate at least two metres above the highest points of the building(s) to be protected. Its location should therefore be determined relative to building superstructures: chimneys, machine and equipment rooms, flagpoles, pylons or aerials. Ideally, these vulnerable points should 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 reach an overall height of 8.50 or 11 m including the lightning air terminal height. They have been specially designed to obviate the need for guying. However, if guying is essential (e.g. when the conductor is fixed with a flat support on the roof waterproofing, or is exposed to particularly strong winds), the guys should be made of Ø 5.6 fibre glass. When metal cables are used for guying, the lower anchoring points should be interconnected with the down conductor by a conductive material of the same type. We offer a range of fixtures adapted to most requirements. Installation specifications are detailed in the individual product data sheets. If several lightning air terminals (ESEAT or SRAT) are used in the outside installation on the same structure, they should be connected by a conductor, except when this has to pass an obstacle of more than 40 cm in height. D ≤ 40 cm: connect ESEATs D ≥ 40 cm: do not connect air terminals When protecting open-air sites such as sports grounds, golf courses, swimming pools, and camping sites, ESEATs are installed on special supports such as lighting masts, pylons, or any other nearby structures from which the conductor can cover the area to be protected. Our software OPR Designer is able to design a complete lightning protection system with all installations details, listing of material, protections areas layout, tests certificates within a complete technical document that is available for the client in pdf format. d ≤ 40 cm d ≤ 40 cm d ≤ 40 cm Interconnection rule when several ESEAT on the same roof ABB OPR lightning protection systems | 15 Lightning capture devices Special cases Antennas By agreement with the user of the antenna, the device can be mounted on the antenna mast, provided that allowance is made for a number of factors notably: – the lightning air terminal tip must culminate at least 2 m above 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 a clamp 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 be used in an atmosphere where the temperature is greater than 120°. Industrial chimney ESE air terminal: – the lightning air terminal should be mounted on an offset mast (2CTH0HRI3501) as far as possible from smoke and corrosive vapours – the mast should be fixed to 2 points as shown in the diagram. To be noted that an ESEAT electronic generator cannot be used in an atmosphere where the temperature is greater than 120°. Single rod air terminal: The lightning air terminals (1 or 2 m) should be mounted on stainless steel supports (2CTH0HPS2630) to enable mounting at a 30° angle. They will be interconnected by a belt conductor positioned 50 cm from the summit of the chimney. When using 1 m air terminal at least two points should be used and placed at intervals of no more than 2 m around the perimeter. When using strike points of at least 2 m in height, the number of points should be calculated to cover the protection radius. Steeple The lightning air terminal have been designed to carry roof ornaments (rooster, weathervane, cardinal points, etc.). The down conductor is then fixed below the ornaments. 2 m minimum ESEAT Ø 35 mm stainless steel ESEAT mast 2CTH070011R0000 500 mm antenna steel hoops down conductor ESEAT offset mast down conductor wind indicator rooster tightening screw cardinal points connecting clamp 750 mm ESEAT base down conductor ESEAT 16 | ABB OPR lightning protection systems Down conductors Overview Down conductors should preferably be made with tin-plated red copper strips, 30 mm wide and 2 mm thick. Lightning is a high frequency current that flows along the periphery of the conductors. For a like cross-section, a flat conductor has a greater periphery. An exception to the above rule is buildings with aluminium cladding on which a copper down conductor might generate an electrolytic coupling phenomenon. Here a 30 x 3 mm aluminium strip should be used or bimetal connection. In some cases where it is impossible to fix the copper strip, a round Ø 8 mm tin-plated copper conductor. In the case where there is a need of mechanical movement of the down conductor use a 30 x 3 mm flexible tin-platted copper braid. Path The path should be planned to take account of the location of the earth termination. The path should be as straight and short as possible avoiding any sharp bends or upturns. Curvature radii should be no less than 20 cm. To divert the down conductor laterally, 30 x 2 mm tin-plated red copper preformed bends should be used. The down conductor path should be chosen to avoid intersection and to be routed along electrical ducts. Shielding the electrical ducts 1 m on each side can be done when it is impossible to avoid crossing them. However when crossovers cannot be avoided, the conduit should be protected inside metal sheeting extending by 1 m on either side of the crossover. This metal sheeting should be connected to the down conductor. However, in exceptional cases where an outside down conductor cannot be installed, the conductor may run down through a service duct, provided that this is used for no other purpose (and subject to agreement with the safety services and inspection organizations). When a building is fitted with a metallic external cladding or stone facing or in glass, or in the case of a fixed covering part of the facade, the down conductor can be installed on the concrete facade or on the main structure, under the cladding. In this case, the conductive parts of the cladding must be connected to the down conductor at the top and at the bottom. The down conductor, if not a copper one, shall be located at more than 10 cm behind inflammable material of the outside cladding if its cross section area if lower than 100 mm². For cross section area of 100 mm² or greater, there is no need to keep a distance between the down conductor and the flammable material. A specific calculation of the temperature increase may be performed to validate a different rule. The same requirements apply also to all inflammable material even on the roof (e.g. thatched roof). Indoor routing When a down conductor cannot be installed outside the structure, it can be fitted inside on a part or on the full height of the structure. In this case, the down conductor must be placed inside a dedicated non flammable and insulating duct. The separation distance shall be calculated also for indoor down conductors in order to be able to determine the necessary insulation level of the dedicated duct. The building operator has to be aware of the resulting difficulties to check and maintain the down conductors, and of the resulting risks of over voltages inside the building. Access of people to the specific cable channel should be avoided in stormy periods or measures of protection as per outdoor down conductors should be fulfilled (see Annex D NF C 17-102 Vers September 2011) including equipotential bondings of floors with the down conductor. Down-conductor bend shapes L d L d L d L L d d L: length of the loop, in meters d: width of the loop, in meters The risk of any dielectric breakdown is avoided if the condition d>L/20 is fulfilled. ABB OPR lightning protection systems | 17 Down conductors Parapet walls When the face of the parapet wall is less than or equal to 40 cm, an upward section in the down conductor is allowed with a maximum slope of no more than 45°. For parapet walls with an upward section of more than 40 cm, space should be allowed or a hole drilled to accommodate a 50 mm minimum diameter sheath and thereby avoid bypassing. If this is not possible, supports of the same height as the parapet wall should be installed to avoid an upturn. Connection The lightning air terminal is connected to the down conductor by a connecting clamp that must be tightly secured on to the mast. The strip will be secured along the extension masts by stainless steel clamps. The conductors can be connected together by coupling strips. Fasteners Whatever the supporting medium the down conductor must be secured by at least 3 fasteners per linear meter. Insulators are used to distance the conductors and prevent contact with easily flammable material (thatch or wood, for example). The fastener must be appropriate for the structure material and installed so as not to impair watertightness and allow the conductor thermal extension. Test joint Each down conductor must be fitted with a test joint or connection link to enable measurement of the resistance of the lightning earth system alone and the electrical continuity of the down conductor. The test coupling is usually placed about 2 m above ground level to make it accessible for inspection purposes only. To be compliant with standards, the test joint should be identified by the words "lightning air terminal" and the "earth" symbol. On metal pylons, framework or cladding, the test joint should be placed on the ground in inspection earth pit about 1 m from the foot of the metal wall to avoid distorting the resistance measurement of the earth connection by inevitably measuring the electrical resistance on the other metallic networks in the building. Protecting flat Between the test joint and the ground, the strip is protected by a 2 m galvanized or stainless steel sheet metal flat fixed by 3 clamps supplied with the flat. The protecting flat can be bent to follow the profile of the building. Warning Notice: Protection measures against step and touch voltages In certain conditions, the vicinity of the down-conductors of an ESE System, outside the structure, may be hazardous to life strip 30 x 2 mm copper round ø 6 or 8 mm 330 lead play 30 or 40 30 test joint protecting at hook down conductor strip lead dowel copper tape 30 x 2 mm 3 screw-in stainless steel clamps on the 2 m of protecting at protecting at even if the ESE System has been designed and constructed according to the above-mentioned requirements. The hazard is reduced to a tolerable level if one of the following conditions is fulfilled: The probability of persons approaching, or the duration of their presence outside the structure and close to the downconductors, is very low. The natural down-conductor system consists of typically more than ten columns of the extensive metal framework of the structure or of several pillars of interconnected steel of the structure, with the electrical continuity assured; The contact resistance of the surface layer of the soil, within 3 m of the down-conductor, is not less than 100 kΩ. NOTE: A layer of insulating material, e.g. asphalt, of 5 cm thickness (or a layer of gravel 15 cm thick) generally reduces the hazard to a tolerable level. If none of these conditions is fulfilled, protection measures shall be adopted against injury to living beings due to touch voltages as follows: – insulation of the exposed down-conductor is provided giving 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 the probability of down-conductors being touched. We propose in our catalogue Warning Notice (2CTH0PSH2009) to prevent touch voltage. 40 cm max 45° max Warning Notice 18 | ABB OPR lightning protection systems Down conductors Lightning stroke counter When the regulations require the installation of a lightning stroke counter, or to know when to make a complete verification of the installation after a lightning stroke. One per ESEAT or SRAT should be fitted. Regarding mesh cage installation one every 4 down conductor should be installed. The test joint around 2 m above the ground. The counter is connected in serial on the down conductor. Lightning stroke counter and recorder is used to store date and time of the impact as well as lightning current values. Meshed conductors On roof Is carried on the roof meshes with conductors of which the width depends on the level of protection and those ones must not be greater than 20 m as follows: It is primarily a closed polygon whose perimeter is adjacent the periphery of the roof, this polygon is then complete by transverse conductors to satisfy the condition on the maximum width of the meshes. If there is a ridge, the conductor must follow it. Air terminals are placed vertically at the highest and most vulnerable points on the buildings (roof ridges, salient points, edges, corners, etc.). They are arranged at regular intervals around the periphery of the roof as follows: – the distance between two 30 cm air terminals should not exceed 15 m – the distance between two 50 cm air terminals should not exceed 20 m – strike air terminals not located on the outer polygon are connected to the polygon as follows: - either by a conductor excluding any upturn if the air terminals is less than 5 m from the polygon - or by two conductors in opposite directions forming a transversal section if the air terminals is located more than 5 m from the polygon. On wall The down conductors are placed on the corners and salient features of the building in a layout that should be as symmetrical and regular as possible. The average distance between two adjacent down conductors depends on the required protection level.

Dangerous sparks may be produced between the two ends of the resulting open loop. There are two ways to avoid this problem: a) Establish an interconnection providing an equipotential bond between the conductor and the metallic networks b) Allow a separation distance between the conductor and the metallic networks. The separation distance is the distance beyond which no dangerous sparks can be produced between the down conductor carrying the lightning current and nearby metallic networks. Because it is often difficult to guarantee that the lightning protection system is sufficiently isolated during installation or will 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 bonding is not used (e.g. when there are flammable or explosive piping net-works). In this case, the down conductors are routed beyond the separation distance "s". Separation distance calculation S (m) = ki.kc.L km where: "kc" is a coefficient determined by the number of down conductors 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 or more conductors. " ki " is determined by the required protection level: ki = 0.08 for protection level 1 (high protection), for very exposed or strategic buildings ki = 0.06 for protection level 2 (reinforced protection, exposed building) ki = 0.04 for protection level 3 & 4 (standard protection) "km" is related to the material situated between the two loop ends: km : 1 for air km = 0.5 for a solid material other than metal "L" is the length between the point at which proximity is measured and the point at which the metallic network is earthed or the nearest equipotential bonding point. S1 L1 L2 S2 air conditioning earthing bar Example An ESEAT with two down conductors protects a 20 m high building with protection level I. – Question 1 : Should an air conditioning extractor located on the roof be interconnected if 3 m away from the down conductor? Length L1 = 25 m. Answer 1 : S1 = 0.08 x 0.75 x 25 / 1 = 1.5 m Since the distance (3 m) between the conductor and the airconditioning system 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 3 m away from the down conductor be interconnected with the conductor, where L2 = 10 m? Answer 2 : S2 = 0.08 x 0.75 x 10 / 0.5 = 1.2 m Since the distance between the computer and the down conductor (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 the separation distances. 20 | ABB OPR lightning protection systems Equipotential bonding Equipotential bonding of external metallic networks The equipotential bonding of external metallic networks is an integral part of the outdoor lightning protection installation just like the down conductors and their earths. All conductive metallic networks located at a distance of less than s (separation distance) from a conductor should be connected to the conductor by a conductive material with a like cross-section. The aerial masts and small posts supporting electrical power lines should be connected to the conductor via a mast arrester. Earthing systems embedded in walls should be connected to the conductor if terminal connections have been provided. Equipotential bonding of internal metallic networks The equipotential bonding of internal metallic networks is an integral part of the indoor lightning protection installation. All conductive metallic networks in the structure (steel frameworks, ducts, sheathing, electrical raceways or telecommunication cable trays, etc.) should be connected to the conductor. This is done by using a conductive material with a cross-section of at least 6 mm² for copper or 16 mm² for steel to connect to equipotential bonding bars installed inside the structure and connected in turn to the closest point of the earthing circuit. Unscreened telecommunication or electrical conductors should be bonded to the lightning protection system via surge arresters. Equipotential bonding of earths This is done by using a conductive material with a cross-section of at least 16 mm² for copper or 50 mm² for steel to connect bonding bar to earth termination system. interconnection with building loop 1 1 2 2 3 3 telephone line protection low voltage power supply protection IT system protection 4 4 TV protection ESEAT OPR ABB OPR lightning protection systems | 21 Earth termination systems Overview Each down conductor in a lightning protection system must be connected to an earth termination system which fulfils four conditions: – The earth termination resistance value International standards stipulate an earth termination resistance value of less than 10 ohms. This value should be measured on the earth connection isolated from any other conductive component. If the resistance value of 10 ohms cannot be achieved, the earth termination is nonetheless considered compliant if it is made up of at least 160 m (protection level 1) or 100 m (protection level 2, 3 & 4) of conductors or electrodes, each section measuring no more than 20 m. – Current carrying capacity This is an often overlooked but essential aspect of lightning conduction. To minimise the earthing system impedance value, a parallel configuration of three electrodes is strongly recommended instead of just one excessively long electrode. – Equipotential bonding Standards require the equipotential bonding of lightning earth 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 utilities Earth termination should be at least 2 m (if soil resistivity is over 500 ohms/m 5 m) distant from any buried metal pipe or electrical conduit, not connected to the main equipotential bonding of the structure. Inspection earth pit The connection parts of an earth termination system (duck's foot connector, earth rod, test joint) can be accessed in an inspection earth pit. Lightning air terminals Ducks foot connector The minimum earth termination system is made up of 25 m of 30 x 2 mm tin-plated copper strip, split into 3 strands buried in 3 trenches at a depth of 60 to 80 cm dug in a fan shape like a duck's foot: one end of the longest strand is connected to the test joint, the two other strands being linked to a special connection known as a duck foot's connector. Earth rods When the site topography does not lend itself to the installation of a duck's foot as described above, an earth termination system can be developed using at least 3 copper earth rods each with a minimum length of 2 m, buried vertically in the ground; the rods should be spaced at intervals of about 2 m and at a mandatory distance of 1 m to 1.5 m from the foundations. protection at 30 x 2 mm down conductor 6 to 9 m depending on soil resistance 1 m from wall depth 60 to 80 cm 8 to 12 m stainless steel clamp NB: the earth termination is covered by a red or orange warning grid DUCK'S FOOT EARTH TERMINATION SYSTEM duck's foot connector Duck's foot earth termination system It is recommended to cover the earth termination system with a red or orange warning plastic mesh. protection at 30 x 2 mm strip 2 m 1 m from wall depth 60 to 80 cm stainless steel clamp NB: the earth termination is covered by a red or orange warning grid 2 m rodearth rod clamp ROD TRIANGLE EARTH TERMINATION SYSTEM Rod triangle earth termination system It is recommended to cover the earth termination system with a red or orange warning plastic mesh.

In this case, the end of each duck foot connector strand is connected to an earth rod. Meshed conductors Duck's foot connector The earth connection is made up of 3 conductors each 3 m minimum 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; the other two splay out at an angle of 45° on either side of this central strand and are coupled to it with a special connector known as a duck's foot connector. The resistance value must be less than 10 ohms. If the resistance value of 10 ohms cannot be achieved, the earth termination is nonetheless considered compliant if it is made up of at least 160 m of electrode in level 1, 100 m in level 2 and 10 m in level 3 & 4. Earth rods The earth connection is made up of 2 spiked vertical rods at least 2 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 to 1.5 m from the foundations. The earth termination systems in a building should be connected together with a conductor with the same cross-section and of the same type as the down conductors. Where there is an existing entrenched earth protection loop in the foundations for the building's 2 m flat electrical installations, there is no need to create a new loop: the earth terminations can simply 0.6 m be interconnected by a tin-plated 30 x 2 mm copper strip. The resistance value must be less than 10 ohms. If the resistance value of 10 ohms cannot be achieved, the earth termination is nonetheless considered compliant if it is made up of at least 160 m (80 m if vertical rods) of electrode in level 1, 100 m (50 m if vertical rods) in level 2 and 10 m (5 m if vertical rods) in level 3 & 4. Earthing system equipotential bonding When the protected building or area has an existing earth termination system for the electrical installations, the lightning earth termination systems should be connected to it. This interconnection should be made to the earthing circuit at the closest point to the down conductor. When this is impossible in an existing building, the interconnection should be made to the earth plate. In this case, the interconnecting conductor should be constructed such that no currents are induced in nearby equipment cables. In all cases, the interconnection should include a device that can be disconnected to enable measurements of the resistance of the lightning earth termination system. This device can be made up of either an interconnection box for equipotential bonding fixed to the main wall of the building, or an equipotential bonding bar located in an inspection earth pit.

The following schedules are recommended: Protection level Visual inspection (year) Complete inspection (year) Critical system complete inspection (year) I and II 1 2 1 III and IV 2 4 1 Note: Critical systems shall be defined by laws or end users. A lightning protection system should also be inspected whenever the protection structure is modified, repaired or when the structure has been struck by lightning. Lightning strikes can be recorded by a lightning strike counter installed on one of the down conductors. ESEAT maintenance kit, a unique solution With its experience of ESEAT development and special testing processes, ABB offers a simple and complete solution: a telescopic 8 m pole supplied with a portable test case to enable simple in situ inspections. The device can be used without dismantling the ESEAT. The following aspects of an ESE System installation should be inspected (see NF C 17-102 September 2011 edition 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 structure needs the installation of additional lightning protection measures – the electrical continuity of visible conductors is correct – all component fasteners and mechanical protectors are in good condition – no parts have been weakened by corrosion – the separation distance is respected and there are enough equipotential bondings and their condition is correct – SPD end of life indicator is correct – maintenance operations results are checked and recorded Complete verification includes visual verification and the following measurements to check: – the electrical continuity of hidden conductors – the earth termination system resistance values (any variation with regards to initial values > 50 % should be analysed) – properly working of ESEAT according to manufacturer procedure. NOTE: High frequency earth system measurement is feasible during installation or in maintenance operation in order to check the coherence between the needs and the installed earth system. The findings of each scheduled inspection should be recorded in a detailed report stating the required corrective measures. Any faults identified in a scheduled inspection should be corrected as soon as possible in order to maintain optimal lightning protection. Initial verification should be performed once the ESE system installation is completed in order to make sure that it complies with the NF C 17-102 standard requirements. 24 | ABB OPR lightning protection systems Lightning air terminal range ESEAT typical installation on masonry building OPR lightning conductor p.26 Coupling accessories p.36 Hooks p.37 Test joint p.39 Duck foot connector p.41 Lightning stroke counter and recorder p.43 Extension mast p.31 Conductor supporting stud p.37 Ruberalu brackets p.37 Antenna mast arrester p.43 Bolted brackets p.33 Protecting flat p.39 Equipotential box p.39 Type 1 surge protective device highly recommended ABB OPR lightning protection systems | 25 Lightning air terminal range ESEAT typical installation on metal cladding OPR lightning conductor p.26 Threaded bases p.35 Test joint p.39 Interconnection box p.39 Lightning stroke counter p.43 Stainless steel clip p.37 Protecting flat p.39 Water deflecting cones p.35 Waterproof Stainless steel clip p.37 Type 1 surge protective device highly recommended 26 | ABB OPR lightning protection systems Lightning air terminal range - Early Streamer Emission OPR, the high pulse voltage, initiation advance lightning air terminal ABB continues to innovate, and has developed a new generation of lightning devices. The new OPR range with increased initiation advance performances, represents further progress in terms of protection, operating autonomy and ease of maintenance. These advancements reinforce ABB's position as International leader in direct lightning protection with over 200 000 installations throughout the world. ABB manufacturing quality The enviable reputation of the OPR has been earned through maintaining a consistently high quality in manufacture. Before leaving the factory, each OPR has been tested for installation breakdown at high voltage, and subjected to a current test that ensures its performance when conducting lightning discharges. The high voltage output pulses at the OPR are also examined to verify correct amplitude and frequency. The OPR is built to withstand the arduous conditions encountered in service, and its ongoing performance can be monitored simply and quickly using the OPR test set. The advantage of initiation advance The unique efficiency of the OPR lightning air terminal is based on a specific initiation advance, well before the natural formation of an upward leader, the OPR generates a leader that rapidly propagates to capture the lightning and direct it to earth. Validated in the laboratory, this gain in time relative to the simple rod provides additional essential protection. Complete autonomy During a storm the ambient electric field may rise to between 10 to 20 kV/m. As soon as the field exceeds a threshold representing the minimum risk of a lightning strike, the OPR lightning terminal is activated. It draws its energy from the ambient electric field the energy required to generate high voltage pulses, creating and propagating an upward leader. No other power sources are required, and no radioactive components are used. Upward leaders Return arc Meeting point A B C D OPR Upward leaders Meeting point A B C D ABB OPR lightning protection systems | 27 RodCheck system: visual strike indicator The aim of the RodCheck system is to give visual information on the intensity of the lightning current caught by 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 therefore contributes to the safety of the people. Indeed a lightning impact may lead to explosion, to fire and consequently be 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 lightning strike current to which it has been subjected. On many sites lightning rods are usually equipped with counters that detect the flow of current without necessarily giving information about its intensity. Only a digital counter could give such characteristics, but it would undoubtedly increase the price of the overall installation. On the other hand, the new edition of the NF C 17-102 also states that from January 2009 it has been compulsory to have two down conductors per ESEAT. Therefore, as the counters are usually placed only on one of 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 an estimate 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 sites and people and provides the right answer to a perfectly justified question: "Has the lightning rod been deeply hit 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 been hit by a lightning stroke RodCheck after lightning stroke of few kA RodCheck after several strokes or one of more than 40 kA Lightning air terminal range Early Streamer Emission Air Terminal - ESEAT 1 2 3 In the examples 2 and 3 we recommend performing a test of the OPR's electronics and afterwards the red ring 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, we strongly recommend a complete check of the lighting rod OPR, including the check of its internal electronic system in case of a lightning impact. An 8 m high pole connected to a test case is needed to carry out the test of the generator. 28 | ABB OPR lightning protection systems Lightning air terminal range Early Streamer Emission Air Terminal - ESEAT Typical applications Industrial sites, buildings, warehouses, where a large protection area is needed.

The earth termination system must fulfil three indispensable conditions: – the earth termination resistance value French and other international standards, as well as the technical requirements of a number of authorities stipulate an earth termination resistance value of less than 10 ohms. This value should be measured on the earth connection isolated from any other conductive component. If the resistance value of 10 ohms cannot be achieved, the earth termination is nonetheless considered compliant if it is made up of at least 100 m of conductors or electrodes, each section measuring no more than 20 m (for level of protection 2, 3 and 4) and 160 m (8 x 20 m) for level 1. – equipotential bonding Standards require the equipotential bonding of lightning earth termination system with the existing earthing systems. – inspection earth pit The connection parts between lightning earth system and electrical system test joint can be accessed by an inspection pit. General earth system Duck's foot earth termination system The minimum earth termination system is made up of 25 m of 30 x 2 mm tin-plated copper strip, split into 3 strands buried in 3 trenches at a depth of 60 to 80 cm dug in a fan shape like a duck's foot: one end of the longest strand is connected to the test joint, the two other strands being linked to a special connection known as a duck's foot connector.

all equal in front of the risk of lightning. For example there is more than 2 million lightning strokes per year on the French territory. They constitute a real risk for all humans and building structures. ABB as lightning protection specialist can offer you a range of lighting air terminals (simple rod or early streamer emission system OPR) in order to protect your facilities and personnel. All these products are developed by the ABB centre of excellence for lightning based in Bagnères de Bigorre - France; they are tested in laboratory as well as in situ to recreate natural conditions in the Pic du Midi (French Pyrenees). Lightning protection specialists? Absolutely. 1TXH000247C0203 - Printed in France (06.2016 PDF) Note We reserve the right to make technical changes or modify the contents of this document without prior notice.
