要約(英語): This paper introduces excellent insulating features of dielectric molded electrodes, studying the flashover and the puncture characteristics under repetitive discharges in SF6 gas. The goal of the study is to clarify the essential breakdown characteristics of thick dielectric-layered electrodes when applied as substitutes for metallic electrodes in high voltage power equipment. The flashover characteristics are investigated by optical measurements in view of the partial discharge onset properties. The puncture characteristics are studied based on the observation of the punctured trace and the utilization factor in the epoxy at the moment of the flashover in SF6. Considering both of the flashover and the puncture characteristics, the remarks on the selection of the appropriate filler in the epoxy is also presented.
