WORKING PRINCIPAL OF THUNDERSTROKE PROTECTOR

THUNDERSTROKE PROTECTOR is an Early Streamer Emission (ESE) air terminal based on the electrical characteristics of lightning formation. The ESE air terminal emits a continuous upward leader with time of advance to anticipate the descent of lightning and capture it before any other object within its protection area.This feature is referred to in the regulations as the advance time of an ESE air terminal (∆T). The earlier the upward leader is triggered, the larger is the distance where the downward leader is intercepted, thus protecting a greater area against lightning (standards limit it to ∆T60μS).

THUNDERSTROKE PROTECTOR ESE terminal offer the highest performance guarantees. It is manufactured in India consisting world class technological system and it is highly competent device.

In a world where buildings and equipments are becoming more complex every day, lightning is a constant hazard. One discharge can damage buildings and cause failures in electronic equipments. It can even provoke fire and lead to serious financial losses.

RADIUS OF PROTECTION (RP)

The radius of protection is the distance between the point where you want to place the rod and the further point from the structure or building we want to protect for calculating the radius of protection. It is very important to get the triggering advance time value of the device.

TRIGGERING ADVANCE TIME (∆T)

The triggering advance time is defined as the difference in triggering time of an early streamer lightning rod and a simple Franklin rod. It is obtained when both rod exposed in the same atmospheric and electrical condition

CALCULATION FOR RADIUS OF PROTECTION

Rp=√h(2D-h) + ∆L(2D+∆L) for>6m.

Rp	:	ESE protected radius
h	:	Height of Protector tip above the area to be protected.
D	:	Triggering distance defined by NFC 17-102, D(m)=10.02/3that is 20 meter at Level 1 (99% protection) 30 meter at Level 2 (97% protection) 45 meter at Level 3 (94% protection) 60 meter at Level 4 (92% protection)
∆L	:	upward leader length gain ∆L(m)=V(m/μS)X ∆T(m/μS)
∆T	:	triggering advance
