Abstract

FEM （Finite Element Method）is applied to the study of the method to the measurement of grounding resistance with short leads. ANSYS

the general FEM software

is used. The earth-surface potential distributions with/without the current electrode are calculated with steady electric field analysis module of ANSYS. According to the compensation theory

the position of test potential electrode to measure the grounding resistance is chosen. Based the analysis result

the grounding resistance of a real grounding grid is tested. The test result is very close to the calculated result

which shows the validity of application of FEM to the grounding resistance measurement. In addition

the situation of grounding grid buried in multi-layer soil is studied

which shows the flexibility and practicability of the FEM.
