More and more conventional grounding systems made of steel are being replaced with copper grounding systems in Asian countries. This paper analyzes the performance of grounding systems made of steel or copper conductors, taking into account the impedances of the ground conductors. A series of computer models simulate grounding systems of different sizes in various soil structures. Numerical results...
A Boundary Element Approach is used to get the numerical computation of grounding system analysis such as the equivalent resistance and the distribution of potential on the earth surface due to fault currents. The results in this paper are produced by the techniques that have been implemented in a computer aided design (CAD) system for grounding grids of electrical substations. The paper investigates...
