Motor surge arrestor
NettetThere are two principal styles of surge arresters. Today, only Metal Oxide (ZnO) Varistor (MOV) arresters are applied. The older type is the silicon carbide gapped arrester and there are many still in service today. Note, however, that gapped arresters more than 25 years old are recommended for replacement because of their age; some propose an ... Nettet25. jul. 2024 · 07/23/2024 11:08 PM. The surge arrester is always placed as close as practically possible to the equipment to be protected. No matter the source of the surge, when it hits the impedance of the motor windings, the surge will essentially reflect and double in magnitude. Your surge protector intercepts this energy, and shunts it to earth …
