Early Streamer Emission (ESE)

  • Based on NFC-17-102-2011 standard 

  • Non-radioactive technology 

  • No external power required 

  • No moving parts 

  • Due to corona formation, release an upward leader 

  • Upward leader is early by 25 μs, 40 μs, 60 μs before downward leader is approaching the structure & channelized the energy to ground 

  • Radius of protection dependent on the height of the mast on which terminal is installed 

  • Level of protection from 84% to 99% with radius upto 79m for level 1 (99%) & 108m for level IV (84%)
