Abstract

MONTANA, Johny Hernán et al. UN_PAT: a software for calculating transient grounding potential. Ing. Investig. [online]. 2006, vol.26, n.3, pp.143-148. ISSN 0120-5609.

This paper presents results from work done at the National University of Colombia and from a PhD thesis written there. This work was aimed at implementing software for analysing the transient behaviour of any configuration of grounding system buried in lineal, homogeneous and isotropic soil. The hybrid electromagnetic model (HEM) was used because it presents high versatility and low computation time. The UN_PAT software was written in C++; it used free libraries with the aim of being free software so that it could be modified and improved in future work. The software results were validated with other software, with results from another analysis model and experimental results; some of these comparisons are given in this paper.

Keywords : grounding system; transient analysis; frequency variation; C++.
