Abstract :
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 f-n distribution patterns are calculated with the integral equation and are compared with those obtained experimentally with an IEC(b) electrode system at various applied voltage frequency (25-1000Hz).
