Today electrode wire in measurement methods of grounding resistance is so long as to result in large influence and large amount of workload . it is great realistic significance that method with short electrode wire for grounding resistance measurement has been proposed 目前实用的接地电阻测量方法大都存在测量引线过长的弊端，过长的测试引线既不利于现场布线还会造成的强烈的电磁干扰，带来很大的测量误差。
