摘　　要：在一起330kV变压器现场交接试验时,主变压器长时感应电压带局部放电测量试验,C相高压侧出现局部放电量超标,现场通过多次试验测量及原因分析,确定了放电位置,经过处理后,该主变压器通过了局部放电测量试验,顺利投运。During a 330 kV power transformer commission test, the partial discharge of the C phase high voltage side in the long time induced voltage with partial discharge measurement was over standard. And then based on measure- ments and analysis the discharge position was located. After treatment of the fault, the power transformer past the par- tial discharge test and was put in service.
