| Abstract: | The ground systems in power plants and substations are the important measures to ensure the safe of equipment and human body and maintain reliable operation of power systems. It is shown in information that the poor grounding has caused failures and resulted in expansion of failure,outage of system and equipment damage both domestically and abroad in recent years. There are 5 main issues related to the ground system in power plant and substations: precision design of ground system;analysis on soil layered structure;diagnosis on corrosion of ground system;resistance reduction of ground system in areas with high soil resistivity and accurate measurement of ground resistance in power plants and substations |
