Lighting Arrester

High Quality Lighting Arresters

Lighting Arrestor is a device used to protect the electronic power systems from the damage. It diverts the lightning to the ground. They help in maintaining the voltage produced by the lightning. We can define a lightning arrester as a collection of billions of microscopic junctions of metal oxide. 

 Their purpose is to limit the rise in voltage when a communications or power line is struck by lightning or is near to a lightning strike.

If protection fails or is absent, lightning that strikes the electrical system introduces thousands of kilovolts that may damage the transmission lines, and can also cause severe damage to transformers and other electrical or electronic devices.

Lightning arresters are used to protect electric fences. They consist of a spark gap and sometimes a series inductor. Such type of equipment is also used for protecting transmitters feeding a mast radiator. For such devices the series inductance has usually just one winding.

Lightning Arresters can form part of large electrical transformers and can fragment during transformer ruptures. High-voltage transformer fire barriers are required to defeat ballistics from small arms as well as projectiles from transformer bushings and lightning Arresters.
