| Abstract: | The grounding resistance is an important technical index of large-scale grounding system and one of the important parameters to measure the effectiveness and safety of geodetic network.It is very important for the safety evaluation of large-scale grounding network to measure the grounding resistance accurately.The importance and design method of large-scale grounding grid in coal power plant were introduced,and the test method and steps of grounding resistance were discussed.Taking a coal power plant in Suzhou as an example,the factors that affect the test of the grounding resistance of geodetic network were analyzed,and the precautions in the test process were given.The test and analysis method had a certain technical guidance for the detection of the grounding resistance of the geodetic network of coal power plant. |
