A device used on electrical and telecommunications systems to protect the insulation and conductors from the damaging effects of lightning. Typically, it has a high-voltage terminal and a ground terminal. When a surge travels along the power line to the arrester, the current from the surge is diverted through the arrester, in most cases to earth.

The antenna is attached to A, and a pipe in the ground is attached to E. The television signal can go from A to B but not from B to C or from C to D. However, when the high voltage of lightning hits, it can easily go through the air from B to C and from C to D and E.
