Analysis of IVAT laboratory grounding system using CDEGS software

Practical tests on grounding systems has proved very costly and pose hazards on operating personnel. Therefore, numerical methods using computers provide the m ost appropriate tool to assess the earthing systems. The research has been conducted with the utilization o f CDEGS software as a tool to si...
