Boundary element approach for the analysis and design of grounding systems in presence of non-homogeneousness

Abstract

A numerical model, based on boundary element technique, is presented for the analysis of complex grounding systems. The model is applied to the analysis of different grounding systems, evaluating its accuracy and reliability. In particular, the presence of extended or localised non-homogeneousness is considered, comparing the results with other approaches proposed in the literature. The merits and the drawbacks of the proposed approach are high-lighted.
