A Theoretical Analysis of Grounding

This study considers three cases, ideal, single point, and ground bus grounding networks. Theoretical analysis is developed by reduction to a composite network suitable in each case. Single point and ground bus grounding networks are evaluated in terms of ideal ground plane. Derivations of these possible networks are provided, with evaluations of these networks with respect to ideal. Derivation of a realizable equipotential plane when fed by two conductors spaced a finite distance apart is developed. Various simplification reducible to closed form are used to analyze the relative merits of a common ground bus versus a steel floor ground plane. Evaluation of the derived relations and their application to the real case including recommendations for improving current grounding practice is provided.
