Sažetak

The improved transmission line (ITL) model of a grounding grid has been already used in engineering practice for a grounding grid transient analysis. This paper offers a progress to the ITL model of a grounding grid based on the finite element method (FEM), where ITL model is developed using FEM applied to the system of multi-conductor Telegrapher equations. In order to check accuracy of the proposed method, the results obtained using ITL approach has been compared to the results calculated using electromagnetic field approach and very good correlation has been obtained.
