Surge Arrestors

Surge Arrestors

Surge arresters are used to protect electrical equipment from over-voltage transients caused by external (lightning) or internal (switching) events, in power transmission and distribution systems. The surge arrester should have a low impulse ratio, so that a surge incident on the surge arrester may be bypassed to the ground instead of passing through the equipment. 

ATEF manufactures surge arrestors up to 132 kV voltage level.
