Abstract
The fall-of-potential method is commonly used to measure the grounding resistance, depending on the measuring area.
In this paper, a numerical simulation was carried out to obtain the grounding resistance. The angle and distance between the current electrode C and potential electrode P were the keys for this calculation, and this was compared with the grounding resistance for the rod electrode having a theoretical solution. It was measured in the electrolytic tank to obtain the accuracy of the estimation.
As a result, the theoretical results were agreed with the experimental values, it was found that this method could estimate the location of the grounding electrode and the experimental value.
