Finite-Difference Analysis of the Potential Distribution around an L-shape Building Base under the Measurement of Grounding Resistance

摘要：

For the first time, a three-dimensional finite difference method （ 3D FDM ） is adopted to simulate the potential distribution during grounding resistance measurements around an L-shape building under different directions and electrodes arrangements.The results show that the distributions of zero potential region with different measurement points and measurement electrodes arrangements are strikingly different when using a straight-line-three-probes method.To obtain more accurate measurement results, scientific and suitable measurement point locations should be properly chosen for the grounding resistance measurement of L-shape buildings according to the surrounding conditions in practical measurements.
