一种有效的接地电阻测量方法

Method to efficiently measure grounding resistances

本文介绍了一种有效的接地电阻测量方法。在该方法中电压测量电极可以在一圆形轨迹上任意位置移动,通过理论推导确定了圆形轨迹的方程。该方法布极位置比较灵活,便于测量布线,克服了0.618布极法和三角形布极法在实际测量中电压测量电极的布极位置受地形影响的问题。

This paper proposes a method to efficiently measure the grounding resistances.In this method the poten-tial electrode can be installed in a circular trace.From theoretical analysis the circular trace equation is derived.The location of the measurement electrodes in this method is very flexible and the layout of measuring wire is very convenient.The restriction of 0.618 and triangle methods on measurement site can be removed by the proposed method.
