Lightning Arrester

A lightning arrester (alternative spelling lightning arrestor) (also called lightning Isolator) is a device used on electric power transmission and telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightning. An arrester is charged and “operates” when working, while the rod simply attracts and diverts incoming lightning. … When potentially dangerous lightning strikes, the arrester activates and diverts the lightning to ground, where it will disperse harmlessly. A surge arrester works by diverting the extra voltage into the earth wire, rather than flowing through the electronic devices, while at the same time allowing the normal voltage to continue along its path.
