Modeling of static and surge properties of the power system pole grounding for various soils

The static and surge properties of the pole grounding system at various soil parameters has been analyzed, taking into account the frequency characteristics, surge parameters, and nonlinear phenomena related to soil ionization during the dissipation of high-intensity surge currents. The analysis is based on the results of numerical calculations that use electromagnetic field theory and method of moments, and known analytical model of high-current phenomena.
