The principle of the Early Streamer Emission Lightning conductor consists in equipping a simple rod with a device which allows a reduction of the excitation time.
The start of the discharge for an ESE Lightning conductor (ascending tracer) occurs earlier than with a simple rod, with an increase in effective length ∆L, thus has a better probability of capturing the tracer going down and of flowing the current of the lightning.
The ESE Lightning conductor allows then to improve the radius of protection of the simple rod.
The ability to favor excitation at lower values of the electrostatic field (hence earlier), enhances the capture probability of conductor.
This capacity gives them greater efficiency in the role of preferential capture points compare to any other point of the building they protect.
Therefore, these lightning conductors offer superior guarantees during low intensity discharges (2 to 5 kA) compared with a simple rod - type lightning conductors, which can only intercept them over short distances.
The zones of protection of lightning conductors are obtained theoretically by plotting the electro-geometric model.
The NF C 17-102 standard defines the radius of protection regarding to the excitation advance and ESE level of protection (given by lightning risk assessment in compliance with the international IEC 62305-2 standard). ESE Lightning rods comply with all the national regulations (formerly I20-2000 and the current I7-2011).
