There 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

Design & Appliion Review of Externally Gapped …

2019/5/25· This is because in old SiC gapped arresters, the MOR consisted of silicon carbide blocks used to limit the power frequency current that followed the surge through the arrester after impulse. These limited current levels protected the gaps from excessive damage and also made it possible for them to end the operation when voltage reached low levels.
