A Method for Studying the Current Field Generated by Interconnected Grounding Systems

In this paper the Authors propose a method for analyzing the current field generated by interconnected grounding systems, with any shape and extension. The method is absolutely general and allows to study the field both in the event of a single line to ground fault (LGF) in one of the interconnected grounding systems and in case of simultaneous line to ground faults in different grounding systems, interconnected to each other. Moreover, this method allows to analyze the grounding systems connected to each other by leaking conductors, as well as to analyze the effects of the faults on metal structures in contact with the soil, such as water pipelines or railway tracks.
