Abstract :
A 3D FE computational tool is developed to compute time-harmonic electromagnetic fields and impedance of substation grounding systems. It is based in the edge AV formulation. The method has been applied in several configurations of presented in the literature. The results are compared with both analytical and experimental data reported by other authors, with overall good agreement
