This paper introduces a novel technique for partial discharge (PD) measurement and analysis: PD-CPWA (PD Current Pulse Waveform Analysis). PD-CPWA focuses on the PD current pulse waveform and its time transition from PD inception to breakdown (BD), which is closely related to PD mechanisms in electrical insulating materials. In this paper, the concept and principle of PD-CPWA are described, and the applications of PD-CPWA to PD characteristics of (1) epoxy spacer samples under thermal and electric combined stresses in GIS and (2) metallic particles contaminated in SF_6 gas on epoxv spacers in GIS are introduced.
