摘　　要：针对电流互感器高压介损现场测量存在的问题,经过不断的实践、总结,提出电流互感器高压介损现场测量的新方法,即:三相被试互感器并联同时加压,小电抗器积木搭接进行串联补偿,激磁侧通过变频电源控制试验频率,避开现场干扰,在工频50 Hz两侧各测一个点,通过求平均值推算出50 Hz频率下的介损数据。According to the problems existed in field testing high voltage dielectric loss of current transformer, through constant practice and summary, this paper presented a new testing method, namely ： parallel step-up to testing 3-phase transformer at the same time, lapping in building-block small reactors for series compensation, controlling test frequency by the power source with variable frequency at exciting side to avoid interference at the field,testing respectively a point on both sides of the industrial frequency of 50 Hz,to get dielectric loss data at the frequency of 50 Hz by calculating average value.
