Abstract

This paper deals with a comparison of individual and common grounding method for potential rise. When a test current flowed through grounding electrode, potential rise was measured and analyzed for grounding method using a electrolytic tank in real time. The grounding electrodes were designed and fabricated with ground rods on a scale of one-eightieth. Potential rises of individual grounding method were higher than those of common grounding method. The distributions of surface potential are dependent on the distance from grounding electrode.
