Lightning is an awesome natural atmospheric phenomenon has the ability to trigger fatal and destructive impact on both life and asset.
Synergy Systech Pvt Ltd focuses on the design, supply and installation to eliminate the direct impact of the lightning spark between the cloud and ground. Our designs encompasses the standards specified in “NFC 17 102” and “IS 2309” for protection of buildings and allied structures against lightning.
The principle behind the ESE lightning arrestors is in the existence of the upward streamer (a.k.a. upward leader). It is a naturally occurring low current electrical discharge phenomenon that exists when a lightning bolt is about to occur in the immediate vicinity.
The lightning bolt starts initially with another phenomenon known as a downward leader, a current electrical discharge that moves down from the thundercloud. As the downward leader nears the surface of the earth, it increases the electric field in the immediate area below it and this cause the emergence of upward streamers from various objects on the earth’s surface (eg. lightning rods, trees, buildings, TV antennae, people etc.). One of these upward streamers will make a connection with the downward leader and as a resultant high current lightning bolt will occur along the connected leader-streamer path.
In the ESE lightning arrestor system, the air terminals can generate these upward streamers earlier than other natural objects on the ground can (hence the term “early streamer”). These artificially generated upward streamers are able to make a connection with the downward leader before any other naturally occurring streamers are able to do so, thus providing a defined path to the lightning flash to the ESE terminal instead of to the building and the ESE terminal in turn conducts the lightning current to ground through the down conductor and finally the earthing system.
ESE Lightning Arrestors are Governed by NFC 17 102 standards.
