LY-ESE3.0 ESE Lightning Rod compare to Conventional Franklin Lightning Rod

ESE (Early Streamer Emission) technology uses the

atmospheric gradient to generate ionization which creates

an upward propagating leader faster than any Franklin

passive rod. The time difference ΔT is the "benefit" of ESE

technology and is known as "early emission"

(microseconds µs).

By reducing the start time, the streamer can be connected

to the descending leader at a virtually located strike point

well above the tip of the ESE lightning rod. This

substantially increases the protected volume (or radius)

and facilitates the protection of large areas, simplifying and

reducing material and installation costs.

Determining the protection radius is key for selecting the

model most suitable lightning rod for each facility based on

the level of early emission (ΔT).

The main standards governing these devices are

NF C 17-102:2011 and UNE 21186:2011. They establish the

relationship between the early streamer emission time

parameter of the lightning rod (ΔT) and its radius of

protection/coverage.
