It is the most direct protective measure to ensure that the staff are not harmed by electric shock; if the grounding wire of the equipment is damaged or the grounding connection is unreliable, it will cause serious injury to the operator and serious damage to the equipment. As the grounding of AC and DC equipment in substations and lightning protection grounding, the grounding grid plays an important role in the safe operation of the system. The grounding grid and the grounding flat iron will be corroded to varying degrees every year, which will cause the grounding resistance of the grounding equipment to change, and the grounding resistance will exceed the normal range, which will cause serious damage to the power system equipment.
为了保证各种电气设备和接地网在规程范围内安全可靠运行，目前，变电运行人员是按规定定期进行接地电阻的测量检查。但是不能使电气设备和接地网完全处于在控状态。 In order to ensure the safe and reliable operation of various electrical equipment and grounding grids within the scope of regulations, at present, substation operators regularly measure and check grounding resistance according to regulations. However, the electrical equipment and the grounding grid cannot be completely under control.
