| Abstract: | The multi-electrode method,which means that there are several current electrodes around the grounding system,is researched in order to avoid many problems from three-electrode method.The details of the three-electrode method are introduced,and the distribution of the electrical field is theoretically deduced and studied respectively using three-electrode method and multi-electrode method.The general formula of the position of zero-potential points and compensation points are deduced when there are N-electro... |
