at the top. the outer shell shall be 58mm dia with lead terminal of 50x6mm
3. The SN Advance Electrode shall be surrounded by “BFC” resistance lowering grounding
minerals to increase the overall conductive surface area in order to lower the ohmic
value and also to minimize the corrosion process.
4. The Advance Electrode shall be of highly conductive
5. BFC – resistance lowering grounding minerals should be of specially developed
electrolytic gel which should be of highly conductive. The compound made of natural
minerals - mixture of Sulphate, Silica, Alumina, Iron Oxide, Titanium Oxide, Calcium
Oxide, Magnesium Oxide, Sodium Oxide, Zinc Oxide, Potassium Oxide, Chloride, Nickel

LIGHTNING PROTECTION
TECHNICAL SPECIFICATIONS FOR LIGHTNING PROTECTION SYSTEMS
Direct Lightning Strike Protection System using ESE Air terminals
The Direct Lightning strike protection system should be based on advance technology Early
Streamer Emission designed to intercept the lightning by anticipating an upward leader by
corona effect before a lightning strike and safely convey the lightning current to earth through
a known and preferred route.
It shall include components like air termination equipment, Air Terminal maintenance/function
test meter, LCD based advanced Lightning Flash Counter, mechanical support, down
conductor(s), and maintenance free earthing system based on Chemical earth enhancing
compound to reduce the earth resistance and a transient earth bonding unit.
The design of the components shall be in accordance with ESE standards NFC-17-102 and also
proven with Indian conditions and traceable to field research, laboratory testing, fundamental
analysis, and statistical levels of the lightning event.
Essential Requirements for Air Terminal.
Air terminal must be Early Streamer Emission type and comply with international ESE
standards such as NFC-17-102 to provide an umbrella protection against lightning strikes
covering a radial distance.
Besides the real lightning tests it should also be tested in a high voltage laboratory for
evaluation of gain in triggering time.
The laboratory test must be in accordance with NFC-17- 102 Appendix-C
The calculation off protection radius of the air terminal must be based on the Rolling
Sphere Methodology (RSM) as per standards.
The air terminal shall be non- radioactive and require no special licensing. The materials
used shall be non-corroding in all weather conditions i.e. rain, thunderstorm, snow, wind, dry
and humid conditions. The air terminal must be totally Autonomous electric device collecting
the energy from the ambient electrical field.
The offered air terminal must work on negative as well as positively polarized cloud
discharges.
The air terminal offered must not be fitted with user replaceable parts/components
such as batteries/transducers/piezo electric cells etc. The operation of the air terminal must be
purely autonomous and do not use batteries or any other external source of power for its
normal operation.
The Air terminal must be capable of handling multiple strokes of lightning currents and
should be maintenance free.

grounding system to a maintenance free low impedance earth pit charged with chemical earth
enhancing compound.
ii. Two down conductors must be used if the height of the installation is more than 28
meters or the horizontal run of the down conductor is mote than the vertical height.
iii Down conductors should be provided for each Air Termination as per ESE standard NFC
17-102 and should be connected to individual earth pits.

down conductor shall be placed in a protective PVC pipe of 3mm minimum wall
thickness so as to avoid mechanical damage and increase human safety.
viii The down conductor should not be subject to bends of less than 0.5 meters radius.
ix. The down conductor shall be secured to the structure/building by approved metallic
fastenings at least every 1 meters.
Earthing & Grounding
i. Earth pits must be made using chemical earth enhancing compounds and must be
maintenance free and tested by CPRI
ii. The earth resistance of the individual earth pit must not exceed 2 ohms static
impedance.
iii. Earthing shall be done with copper earth tube of 2.5” dia, 8fts long, 1.6mm thick at least
3 meter depth and back filled with Chemical earth enhancing compound.
iv. A 25x3mm copper strip must be securely connected to the earth tube and extended
upto the earth pit chamber through a 40mm dia class B GI pipe.
v. A minimum quantity of 20 Kg of Earth enhancing compound must be used per earth pit.
vi. An earth pit chamber made of lockable plastic material must be used as inspection
chamber.
vii. General arrangement for chemical earth pit is mentioned as annexure - B
Transient Earth Bonding Unit.
All the equipments, structures & earth pits should be bonded together to form one complete
system to ensure that there is complete continuity in the lighting protection system and thus
eliminating the possibility of any flashover. However, bonding of Lightning, electrical and
communication earthing should be made through a Transient Earth Bonding Unit to keep the two
earths separate during normal conditions. Transient earth bonding unit should be enclosed in an
IP68 Explosion proof and weather proof non corrosive enclosure.
Technical Specifications for Transient earth Bonding Unit.
Operating voltage : up to 230V DC
Firing voltage : 230V DC
Impulse firing voltage : <600V at 1kV/us
Surge rating : 20KA 8/20us
Rating : IP68
