Abstract

This study proposes and develops a mathematical formulation that helps to clearly understand the current and voltage distribution in the damaged and physically integrated horizontal elements of grounding systems. This realistic mathematical model of the grounding device with damaged elements will help to estimate the current and voltage distribution at the generating substation and will improve safety conditions for staff and equipment and reducing damages associated with equipment failures. It will also provide the basis for developing novel grounding integrity detection techniques.
