摘要

The improved transmission line (ITL) model of a grounding grid has been already used in engineering practicenfor a grounding grid transient analysis. This article offers a progress to the ITL model of a grounding grid onnthe basis of the finite element method, where ITL model is developed using finite element method applied tonthe system of multiconductor telegrapher equations. To check accuracy of the proposed method, the resultsnobtained using ITL approach has been compared with the results calculated using electromagnetic field approachnand very good correlation has been obtained.
