How ESE System Works LPS designed in accordance with NF C 17 102 : 2011

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 ESE 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.

Lightning air terminal range Early Streamer Emission Air Terminal - ESEAT

Calculating protected areas The radius of protection Rp of an OPR is given by French standard NF C 17-102 (September 2011 edition). It depends on the ESEAT efficiency ∆T of the OPR measured in the high voltage laboratory, on the levels of protection I, II, III or IV calculated according to the lightning risk assessment guides or standards (NF C 17-102 annex A or IEC 62305-2, guides UTE C 17-100-2 or UTE C 17-108) and on the height h of the lightning air terminal over the area to be protected (minimum height = 2 m). The protection radius is calculated according to Annex C in French standard NF C 17-102. For OPR 60, limiting the value of ∆T used in the protection radius calculations to 60 µs (limited 60 µs in accordance with the paragraph 5.2.2 of the NF C 17-102 standard).

What is Lightning Protection System?

Lightning is a gigantic electrical spark!

It has been measured Lightning discharges contain from several thousand amps to over 300,000 amps – enough to light half a million 100 watt bulbs!

The function of an external lightning protection system is to intercept, conduct and disperse a lightning strike safely to earth. Without such a system a building’s structure, electronic systems and the people working around or within it are all at risk.

Comparison between two major methods of LPS

f766353e-33c9-4891-8e2f-ef1a47b5cff7

Conventional (Franklin Rod Method) LPS

  • Custom Designed for individual building
  • Require complex engineering to function properly
  • Single air-terminal can cover up to 50 ft. radius
  • Two classes of conductors used: Class I and Class II
  • Depending on building perimeter, two or more grounding facility required
  • Highly recommended for industrial sheds and buildings
  • Traditional and proven technology
