Panzhihua Iron And Steel Power Plant To Network The Impact Of Ground Measurement Study

In power systerm, the accuracy of measurement of grounding grid is directly related to electrical equipment and personal safety. Lightning or other causes of the high current into the ground, the grounding resistance value is relatively large, that may result in grounding potential rise in vain to make a ground power system short-circuit fault, so would be a threat to the safety of the staff , also cause damage to electrical equipment .In this paper, the plant ground grid power system has been studied. Mainly divided into two:1. Study the impact of the power plant by measuring grounding resistance. We used the impact of the current application as a mainly measure current into the grounding grid. We me asured the impulse grounding resistance and ground potential impact. In the tests, wesummed up experience and improved measurement methods. We analysed the measured data of netwo rk processing and detailed analysis of the local grounding grid. The measurement method is feasible in practical engineering.2.By using the actual conductor distribution network, calculated and analyzed the grou nding grid, then used software to map out a ground network of potential distribution maps. The network distribution maps clearly reflects the visual impact of potential distribution in networks. The practical significance of the assessment of ground network.
