A surge arrester, as the name suggests, is a device that protects other electrical equipment by "arresting" or discharging surge currents brought about by external (e.g. lightning) or internal (switching events) forces. It is also called a surge protection device (acronym: SPD), or less commonly, a voltage surge suppressor (TVSS).
