用部分电容法计算和消除相间干扰

Calculating and Eliminating Coupling Current Using the Partial Capacitance Method

提出了一种分析金属氧化物避雷器（ＭＯＡ） 相间耦合电流的简化计算模型，并且运用部分电容法算出了不同电压等级下的相间耦合电流，计算结果与实测数据一致，为在线监测ＭＯＡ避雷器减小相间干扰提供了方便可行的办法。

A kind of simple model to analyze the coupling current between phases of Metal Oxide surge Arresters (MOA) is presented,and the coupling current in differet voltage degree using the partial capacitance method is calculated.The result of calculation is accorded with the practically measuring data.So it offeres a convenient and feasible way to minish the coupling current between phases when on line monitoring the MOA.
