摘要
在分析了金属氧化物避雷器(MOA)数学模型的基础上,详细介绍了谐波分析法的理论基础和MOA带电测试系统的组成。通过对现场带电测试数据的分析,证实了使用谐波分析法进行避雷器带电测试的必要性。最后指出使用谐波分析法进行避雷器带电测试更能反映避雷器当前真实的运行状况,对于保证电力系统的安全运行具有重要价值。
Based on the analysis of the model of MOA（Metal Oxide Surge Arredter）,the paper introduces the theoretical foundation of harmonic analysis and the composite of MOA on-line measurement system particularly.According to the analyse of the datas,which is measured on-line,the paper approves the necessary of the on-line measurement of MOA,which is based on the harmonic analysis method.Findly the paper gets the conclusion that the on-line measurement of MOA based on harmonic analysis method can reflect the actual status more dependable.The results possess that the method plays an important role in the power system.
