A lightning arrester is a device used on electrical power systems and telecommunications systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrester has a high-voltage terminal and a ground terminal.When a lightning surge (or switching surge, which is very similar) travels along the power line to the arrester, the current from the surge is diverted through the arrestor, in most cases to earth. lightning arrester may be a spark gap or may have a block of a semiconducting material such as silicon carbide or zinc oxide. Thyrite was once a trade name for the silicon carbide used in arresters.
