Some Useful Measures to Study Efficiency of Grounding Systems - Case of Simple Configurations

The paper proposes some simple measures for studying an efficiency for grounding systems in the frequency domain. These measures are: the ratio of leakage current and injected current and the power leakage through the surrounding soil. Being opener to the subject this work studies rather simple geometries of grounding systems: semi-spherical and horizontal grounding electrode, respectively. Some illustrative results are given in the paper.
