Research on effects between grounding module and grounding eesistance

One of the methods to decrease the resistance of ground grids to safety regulation is to use the grounding module at present. In the first part, the ingredients and the principle of resistance reducing of grounding module were introduced. Then, set up the model of ground grids and simulated under different situations like the different fixed position of grounding module, ground grids acreage and soil resistivity by CDEGS software.. Regarded that these changes were influential. At last, some practical advised about grounding module were given.
