摘　　要：运用ANSYS Maxwell和EMTP软件联合仿真,将"场"和"路"相结合的方法用于计算500 kV MOA带电测量相间干扰问题,并通过实际运行数据加以验证,为MOA在线监测减小相间干扰提供了理论依据和切实可行的办法。A method combined with ＂field＂ and ＂circuit＂ is proposed to calculate the interphase interference during live line measurement of 500 kV metal oxide arrester （ MOA ） , which is verified by the joint simulation with ANSYS Maxwell and EMTP. And it provides theoretical basis and practical way to reduce interference effects.
