        "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."
