ABSTRACT:
A high voltage surge arrester comprise plurality of low voltage surge arresters coupled together in a series parallel network, the low voltage arresters being of a high strength polymeric type consisting of a solid core of varistor blocks encased within a glass fibre reinforced plastics shell and housed in a shedded polymeric housing, and the series parallel network consisting of a plurality of series connected stages each of which comprises a generally annular mounting plate formed with an integral corona discharge suppression ring and a plurality of the low voltage surge arresters mounted to the mounting plate at uniformly spaced apart positions. The subject high voltage, series parallel surge arrester can replace conventional station class porcelain housed surge arresters, which are expensive, troublesome to transport and instal and liable to electrical problems, and avoids all of these problems whilst providing numerous significant advantages.
