Lightning Arrester

A lightning Arrester is a metal rod or metallic object mounted on top of a building, electrical power systems and telecommunications systems electrically bonded using a wire or electrical conductor to interface with ground or "earth" through an electrode, engineered to protect the building and the electrical power system from the damaging effects of lightning strike. If lightning targets preferentially strike the rod and be conducted to ground through the wire, instead of passing through the building, where it could start a fire or cause electrocution. The typical lightning arrester has a high-voltage terminal and a ground terminal. A lighting arrester made from GI rod and copper bounded rod in form of single point and multipoint's system.
