摘要
6电极法是在被测电极的四周对称设 4个电流极 ,在被测电极与电流极之间距离的约 0 .8处 (靠近电流极一侧 )设置电压极的测量方法。理论分析和测量结果表明 ,该方法不仅提高了接地电阻测量的准确度 。
At the present time, the fall-of-potential method is widely adopted for measuring earth resistance. This method needs two auxiliary electrodes which are of potential and current electrode. It is required that two auxiliary electrodes are placed at enough distances from measured earth electrode. But in worksite, usually these auxiliary electrodes could not be put in a specified position. This paper proposes a new method for measuring earth resistance. The amount of auxiliary current electrode will be increased and they are placed symmetrically around the measured earth electrode. Using this method, the distances of auxiliary electrodes could be reduced.
