电缆终端局部放电带电测试方法的比较与应用

Comparison and Application of Partial Discharge Test Methods on Cable Terminal

文章针对电缆终端局部放电带电测试方法,结合现场应用情况,分析比较了现有的几种测试方法的可操作性、测量灵敏度,同时在实验室建立了3种常见局部放电类型模型并获得其超声波信号特征,为各种类型电缆终端局部放电带电测试工作的开展提供参考。

Combining with field application results, this paper compares several existing testing methods of cable terminal PD test on the operability and the sensitivity, at the same time it builds up three com- mon types of partial discharge models in the lab and gets the ultrasonic signal feature, it also provides the reference to field PD test of the various types of cable terminals.
