摘　　要：变压器内部绝缘的缺陷是引起变压器局部放电的主要原因。局部放电给变压器绝缘带来极大危害。测量局部放电的方法较多，本文着重讨论脉冲电流法及在线监测。The defect of transformer inner insulation is the main element causing the part discharge of the transformer. The part discharge will bring the greatest dangers to trans former insulation. There are more methods to measure the part discharge, but this paper mainly discusses the pulsating current and the online monitor.

关 键 词：变压器 局部放电 放电测量 评价
