Abstract (en)
A surge arrester for use in connection with a high voltage electric power distribution system includes a housing, a plurality of metal oxide varistor blocks disposed within the housing, a ground lead disconnector, and a conductive stud which electrically couples the ground lead disconnector to the varistor blocks. The surge arrester has a metal support arm disposed between the housing and the ground lead disconnector, and isolating members for electrically isolating the metal support arm from the conductive stud. The isolating members comprise a first insulative member disposed between the metal support arm and the housing, and a second insulative member disposed between the metal support arm and the ground lead disconnector. In the case of arrester failure, the isolating members prevent high voltage from being provided to the metal support arm. <IMAGE>
