摘　　要：采用直线法测量大型地网接地阻抗时,两导线间的互感将会对测量结果造成影响。文章介绍了一种计算方法,该方法能够有效地去除测量大型地网接地阻抗时电压线与电流线之间的互感,从而获得该地网准确的接地阻抗值。In the straight-line measurements of the grounding impedance, the mutual-inductance between two conductors will impact on the measurement results. This article describes a computational method that can effectively remove the mutual-inductance between the voltage line and the current line in the grounding impedance measurements, so as to obtain the exact grounding impedance values.

关 键 词：接地网 接地阻抗 互感 消除
