摘要
本文讨论了通过测量泄漏电流确定氧化锌避雷器绝缘状况的几种方法。提出了一种基于泄漏电流谐波分析的新方法,它的主要优点是对系统电压谐波的低灵敏度,减小系统电压谐波对测量结果的影响,因而获得很好的效果。
Discussing on several methods according to the leakage current to confirm the insulation status of ZnO arrester,in this paper,the author presented a new method based on harmonic analysis of leakage current.Main excellence of which is that sensitivity to system voltage harmonic is lower,so the influence from system voltage harmonic to measuring result would reduces,and a very good effect would be get.
