摘　　要：阐述了运行中金属氧化物避雷器(MOA)状态检测方法,即停电例行试验、在线监测、带电试验,并分析了各检测项目的试验数据判析方法。提出运行中MOA状态检测应以带电试验为主,其他方法为辅参考MOA运行工况、检修情况进行。在进行MOA性能评价时,应综合分析判断各种检测数据,基于比较法进行全面、正确的评价,以提高MOA安全运行的可靠性。State detection method for Metal Oxide Arrester（MOA）in service is described, that is,power outages routine test, online monitoring, live test, and the analysis methods for the test data of each test item are analyzed. It is proposed that for the state detecting of MOA in service, live test should given priority, and other methods of service according to the MOA operation maintenance condition. In the performance evaluation of the MOA, various test data should be comprehensive analyzed and judged based on comparison method, in order to improve the reliability of the MOA safe operation.
