摘要
随着电力系统规模的日益庞大,对电力设备的可靠性要求越来越高。局部放电是导致电力变压器绝缘损坏甚至故障的主要原因。文中简要分析了局部放电产生的原因,阐述了现存检测方法的不足,指出了变压器中局部放电定位的重要作用。
With the electric power system becoming more complex, the demand for reliability of power equipment be- comes more and more strong. Partial discharge（PD）is th
e main reason for insulation damaged or failure in power transform- er. This paper briefly analyzed the causes of the PD, summarized the existing PD detection methods and its shortage. And pointed out the important role of PD location in transformer.
