摘要
针对出厂试验中某500kV变压器长时感应耐压试验局部放电量超标的情况,采用多端子测量法将局部放电源定位在高压套管上,对故障套管进行了分析与处理。
According to the situation of partial discharge exceeded in a 500 kV transformer,the partial discharge source is located in the high voltage bushing with multi-terminal measurement method. The fault is analysed and treated.
