This book provides electrical and electronic engineering undergraduate and graduate students and trainees with practical information on grounding-system parameters, and on different methods for measuring soil resistivity and ground resistance. It also presents some real-world studies, which enhance the learning experience. It discusses electromagnetic field theories to explain ground resistance modeling using different sizes of electrodes. Furthermore it includes CYME GRD software for simulation of soil resistivity and grounding grid design, and considers some fundamental concepts of power systems to clarify other topics related to the grounding system.
