Research and Analyzes of Effects of Earthing Module to Grounding Resistance

At present, how to decrease the resistance of ground grids to safety regulation is very important in grounding programme, using earthing module is one of the effective methods. In this paper, the ingredient and the principle of resistance reducing of earthing module were introduced firstly. Then, set up the model of ground grids and simulated them by grounding software under different situations. Finally, the impulse earthing resistance will be worked with and figured out the relationship between ingredient and impulse earthing resistance.
