摘要

首先介绍了由“直流分量法”、“交流叠加法”和“损耗电流测量法”三者结合起来的综合判断方法

然后重点论述了交流叠加法的具体实现方案。基于3种方法的综合应用

制成的装置可以在不改变电力系统接地方式的情况下实现XLPE电缆水树老化状况的在线检测。

Abstract

In this paper

a comprehensive method combined by DC component method

AC superposition method and loss current measurement method are described at first .Then

how to realize the AC superposition method is emphasized.With the synthet ical use of three methods

an equipment is set up and can monitor the deteriorati on of water-tree in XLPE cable on line without changing the grounding mode of th e electric power system.
