OS4-3 Transient grounding behavior: field vs. transmission line theories considering frequency-dependent soil parameters

This paper assesses the transient behavior of electrical groundings systems due to direct lightning strikes under the assumptions of constant and frequency-dependent soil parameters. It is known that this is a parameter that affects the overvoltages of the insulation rope and the increase of the soil potential (GPR). In this case, two configurations are analyzed […]
