A station class surge arrester includes a module assembly. The module assembly includes at least one metal oxide varistor (MOV) disk and a pre-impregnated composite that is applied around the at least one MOV disk. The pre-impregnated composite is capable of withstanding an 80 kA fault current for 12 cycles. The station class surge arrester also
Zinc oxide surge arresters are used to replace capacitive elements for voltages below the pick-up voltage of the surge arrester. Advantageously, the surge arresters may be provided in an alternating current network to provide a high degree of protection against transient disturbances without increasing cost.
