摘要

由于阻性泄漏电流很大程度上能反映氧化锌避雷器的健康状况

因此在线监测阻性泄漏电流尤为重要

分析比较了MOA的几种在线监测方法及几种测量方法存在的问题

指出了两种影响测量精度

但未引起重视的干扰源

并对近些年国内外此方向的发展动态和未来的发展趋势加以综述。

Abstract

It is important to monitor the state of Metal-Oxide Arresters （MOA） on line

especially the resistive leakage current

which reflects the MOA’s health to a great extent. Several online monitoring methods for MOA are analyzed and the existing problems are highlighted. In addition

two sources of disturbance which influence the measuring accuracy are pointed out. Some research results coming from the last documents in the field have been collected and the future tendency is indicated.
