A s paper investigates the performance of grounding electrodes buried in the close vieihty of small soil heterogeneity, by using 2D and 3D finite element modelling. The proposed methodology enables consideration of electrode geometry effects which are not taken intp account in standard analytical grounding system representation, The results are compared to those found in the literature or obtained by standard programs. Znder Terms-Grounding Systems, electrodes, finite element method, surface potential.

cases as the current distribution along the conductor is even more non-uniform. The finite element method enables efficient modelling of both the electrode geometry and the surrounding soil heterogeneity, that is why it has been adopted for the grounding system representation. This method has been applied to model a two dimensional grounding system geometq at low fiequencies consisted of a vertical rod buried in a layered soil. The results obtained have been compared to those of a standard code based on thin wire approximation theory [71. The case of a 3D grounding system geometry adopted usually when foundation grounding systems are used has been considered. The employed 3D finite element model results have been compared to those obtained by a commercial software [A.
The performance of grounding electrodes buried in the close vicinity of small soil heterogeneity has a considerable practical importance. As the behavior of small or concentrated grounding systems is not very different in high fiequencies compared to low frequencies, it is usually II.MODELLING TECHNIQUES suilicient to evaluate potentials produced by a DC current. Two Werent modeling procedures have been examined, In many practical cases, analytical modeling of grounding systems is used based on thin wire approximation theory and their results compared and discussed [1],[2]. Such a methodology uses closed form solutions and A, Thin WireApproximation Method enables fast computation of grounding system performance When the shape of the grounding electrodes used is in cases involving complex electrode structures [31,[41. Although all typical electrodes practically satisfy the cylindrical while the length of the cylinder is much larger assumptions of thin wire approximation, such techniques than its radius (1>7a) and its radius is much smaller than the may provide imperfect representation of certain aspects of wavelength (a
