氧化锌避雷器带电测试方法应用分析

Applications and Analysis of Hot Line Detecting Methods for MOA

氧化锌避雷器(MOA)带电测试可分为参考电压信号法(补偿法)和不取参考电压信号法。依据对参考角度设定的不同方式,不取电压参考信号法又可分为角度提前设定、电流法设定和依据统计原理设定。通过现场测试,比较分析了不取参考电压信号法的不同角度设定方式测试结果的差别。总结其相关规律,且为试验人员今后更好地判断试验结果提供了参考。

According to whether the reference voltage signal, the hot line detecting methods for MOA can be divided into the method with a reference voltage signal （Compensation Act ） and the method without a reference voltage signal. Based on the different ways to set the reference angle, the method without a reference voltage signal can be divided into the angle setting in advance, setting by the current and based on the statistical principle. Through field test, the article compares and analyses the disparities of the measuring results. By summarizing the related laws, this article could provide a reference for the testing personnel in the future to better judge the test results.
