Estimation of Actual Earth Resistance in Complex Earthing Networks: A Case Study for Telecom Towers

In this paper, we address the problem of estimating the actual earth resistance of a complex earthing system. Specifically, we model the earthing network using ANSYS Electromagnetics in the finite element domain. Then, we compare the theoretical and simulated results to estimate the earth resistance by analyzing the relationship between them. Finally, we validate the effectiveness of the proposed method using simulation and experimental results.
