实用“零序电流互感器法查找电缆故障点”

A Practical ZCT Search Method for Cable Failure Points

论述工矿企业交联高压电力电缆的接地故障查找,结合笔者多年现场工作实践对交联电力电缆在接地故障查找方面存在的问题进行了反思,提出了一种简单实用可靠的"零序电流互感器查找法",对方法原理进行了论述并通过实例进行了验证。

The search of grounding faults of cross-linking high voltage power cables in industrial and mining enterprises is described. Problems in ground fault search of cross-linking power cables are introspected in combination with many years of site practice of the authors.A simple, practical and reliable “zero sequence current transformer (ZCT) search method”is put forward and the principle of the method is discussed and verified through actual cases.
