ELLIPS Early Streamer Emission (ESE) lightning rod is the result of over 10 years of research and laboratory experiments and field test. Combining advanced materials and technologies, ELLIPS ESE lightning rod is thought out to optimize the whole of your lightning protection system. Each ELLIPS ESE lightning rod can be test  by wired- controlled tester or remote- controlled tester ( ELLIPS Contact option ). ELLIPS aesthetics and colors allow its integration within all possible drafts and structures ( 8 colors available - not effect on operation ).

Calculation for Protection Fields of Active Lightning Rod
The protection fields of Active Lightning Rods can be calculated
with the formula below.
In this formula;
Rp: radius of protection in a horizontal plane situated
at a vertical distance h of the rod.
h: height of the top of the point of the rod above the area to protect.
D: Lightning advancement step or leaping interval of lightning along the way.
-For this reason it is the protection level parameter.
"D'' Value;
-For level I protection D=20 m
-For level II protection D=45 m
-For level III protection D=6 m
