摘要
为了消除感应电压对输电线路绝缘核相测试的干扰,介绍了一种利用串联谐振抗干扰的方法,与传统试验方法测试结果相比,采用串联谐振抗干扰方法后,线路测试结果准确并有着良好的一致性,同时解决了在较高感应电压下不能测试输电线路绝缘电阻的问题。
In order to eliminate the interference of induced voltage in the test of insulation phase checking for transmission lines,an anti-interference method of serial resonance is described.Through the comparison with the results of traditional test methods,it shows that the proposed method results are accurate and consistent and solves the problem of being unable to measure the insulation resistance of transmission lines at high induced voltages.
