摘要
作为电缆局部放电的有效监测手段,脉冲电流法进行局部放电测试的经验及方法日益被深化和掌握。基于高速采样装置采集的电缆接地端脉冲电流信号,针对电缆的非终端和中间端位置发生的局部放电现象,探讨了一种可大致定位电力电缆局部放电位置的方法。
As an effective monitoring method, cable partial discharge pulse current method for partial discharge test experience and methods are increasingly deepening and master. Based on high- speed sampling devices to collect pulse current signal cable grounding end, among the terminals for the cable and the location of partial discharge phenomena, discusses a kind of power cable partial discharge location can be roughly positioning method.
