Abstract
[Abstract] In this work we present a numerical formulation for the analysis of a common problem in electrical engineering
practice, that is, the existence of transferred earth potentials
in a grounding installation [1]. The transfer of potentials
between the grounding area to outer points by buried
conductors, such as communication or signal circuits, neutral
wires, pipes, rails, or metallic fences, may produce serious
safety problems [2]. In this paper we summaryze the
BE numerical approach and we present a new technique for the transferred potential analysis. Finally, we show some examples by using the geometry of real grounding systems in different cases of transferred potentials.
