| 摘 要： | Partial discharge based risk assessment method has rapidly developed as an effective diagnosis method in oil/pressboard insulation system.The temperature in field power transformer is variable according to loading and the PD properties in insulation are also variable in different temperature.In order to assess the influence of temperature on partial discharge properties in oil/pressboard insulation system,a partial discharge testing system with temperature adjusting function was adopted in this paper.The partial discharge data obtained from the experimental work were presented in phase-resolved PD(PRPD) pattern analysis and pulse sequence analysis(PSA).The single pulse in time domain at different temperature is also analysed in this paper.
