Optimum design of substation grounding in a two layer earth structure: Part IIߞComparison between theoretical and experimental results

In a previous paper [1] the authors have presented the theoretical basis of their computer program which calculates grounding electrode performance. This paper compares experimental results obtained in a scaled down two layer earth model [2] with the analytical results for different forms of usual ground electrodes, it compares also the authors method with the conventional methods used currently in the industry.
