| Abstract |
This paper deals with the potential interferences between ground rods. To propose a method for reducing the potential interference caused by grounding electrodes, the theoretical analysis and the reduced scale model tests, which are related to the measurement and computation of ground potential rise and potential interference caused by actual-sized grounding electrodes where current is injected, were carried out. The ground potential rise and potential interference coefficients were measured by using the hemispherical water tank grounding simulator and calculated by CDEGS software as a function of the distance between grounding electrodes. The ground potential rises and potential interference coefficients strongly depend on the distance between grounding electrodes, and the measured results were compared with the computer calculated data and were known in good agreement. |
