摘要：

A novel technique for partial discharge (PD) measurement and analysis (PD-CPWA: PD Current Pulse Waveform Analysis) is developed and introduced in this paper. PDCPWA is expected to be utilized to discuss PD mechanisms and physics in electrical insulating materials, focusing on the PD current pulse waveform and its time transition from PD inception to breakdown (BD). In this paper, the concept and principle of PDCPWA are described, and the applications of PD-CPWA to (1) epoxy spacer samples under thermal and electric combined stresses in GIS, (2) creepage PD on epoxy spacers in SF6 gas and (3) liquid nitrogen / polypropylene laminated paper composite insulation system for high temperature superconducting cables are introduced and discussed.
