Different calculation methods and experimental validation for various ground electrode types

Abstract

A comparison between results obtained using different calculation methods, simulations and experimental results for different grounding electrodes of same dimension and characteristic is carried out in the paper. The procedures include Method of Moments (MoM), Point Matching Method (PMM) and standard equations for the design of a grounding system. Calculation for the grounding grid system, vertical and horizontal rod electrode was performed by using point matching method. Obtained values are compared with simulation results and with experimental results. Simulations where performed by COMSOL program package application. The potential distribution and resistances are determined.
