要約(英語): Partial discharge (PD) phenomena are the major factors of insulation degradation to determine the life of high voltage power apparatus, and have been investigated from various viewpoints. In this paper, authors proposed an integral equation in order to explain the complex characteristics of partial discharge using very simple three-capacitance model with several numerical solutions at various applied voltage conditions. The φ-n distribution patterns are calculated by the integral equation and are compared with those obtained by Mote-Carlo Simulation. PD characteristic for low voltage conditions, in which only one PD pulse occurs within a half cycle of applied AC voltage, was already analyzed analytically. In this paper, PD characteristics have been analyzed for more complicated conditions in which multiple PD pluses occur in a half cycle of applied AC voltage as well as asymmetric electrode conditions.
