Abstract

A dead front arrester is provided with resistively graded gap assemblies and metal oxide disks in series to improve arrester performance during overvoltage conditions. The arrester includes a polymeric cover having an inner annular recess therein, which may be used to increase cover dielectric strength, aid in pressure relief, hold hygroscopic materials, or to increase heat transfer away from the resistive components of the arrester. The gap assemblies and other resistive elements may be hermetically sealed in a subassembly prior to assembly into the arrester, to prevent moisture contamination thereof.
