Abstract
The grounding systems provide a low resistance path for fault or normal currents into the earth. The material for reducing ground resistance is buried around the grounding electrode to increase its effective size of the electrode and thus to obtain low ground resistance. Increasing the contacting area with the grounding electrode is effective for lowering the ground resistance in soils. Using this idea the conductive expansion ground resistance reducing material was developed. In this paper experimental data has shown that the ground resistance reduction method using proposed material is superior to using a typically available commercial ground resistance reducing material.
