Abstract
The safety of the persons, the protection of the equipment and the continuity of the power supply are the main objectives of the grounding system of a large electrical installation. For its accurate design, it is essential to determine the potential distribution on earth surface and the equivalent resistance of the system. In this paper, we present a numerical approach based on the Boundary Element method for grounding analysis in layered soils. The feasibility of this formulation is discussed with its application to a real grounding system embedded in different kinds of layered soil models.
