电力电缆绝缘性能检测方法分析

ANALYSIS ON THE METHOD OF DETECTING ELECTRICAL CABLE,S INSULATION CHARACTRISTICS

对电力电缆不带电和带电检测的常用方法进行了比较分析。通过比较,在不带电检测方法中,二次脉冲法是一种比较好的方法;在带电检测的方法中,交流电压迭加法是目前比较好的一种方法。

The normal off-line and on-line detection of electrical power cable is analysed in this paper. By comparison , the second fluctuation is the better method in off-line detecting methods,the AC voltage addition is the better method in on-line detecting methods.
