摘　　要：介绍不同干扰信号对局部放电的影响,提出局部放电试验系统外部干扰和内部干扰的排查方法,结合一起500kV变压器现场局部放电试验中的干扰排查实例,分析试验干扰排查的过程及干扰源判断方法,为现场局部放电试验干扰信号处理提供借鉴。The effects of different interfering signals on the partial discharge are introduced. A method for the investigation of external disturbance and internal interference in partial discharge test system is proposed.Combined with 500 kV transformers on-site partial discharge test in the case of interference, analysis of the process of interference investigation and interference source judgment is put forward to provide reference for the field partial discharge test interference signal processing.
