摘要

针对一起MOA全电流超标事件进行了跟踪分析。结合红外测温、在线监测数据以及气象特征等信息

确认数据超标原因为表面污秽引起。对表面污秽引起一系列测试数据的变化做了原理分析

指出如何有效区分表面污秽与MOA故障表现出的特征差异

从而避免对MOA状态做误判断。

Abstract

An incident that the leakage current of metal oxide surge arrester（MOA） is higher than specified value is analyzed.Combination of infrared temperature measurement

on-line monitoring data and climate features

the cause of the above incident is due to surface pollution of MOA.The variation of the testing data caused by surface pollution is analyzed in principle.How to effectively distinguish the feature difference between the surface pollution and MOA fault is pointed out to avoid misjudging the condition of MOA.
