摘要

The transient characteristics of a grounding grid is very important for the safety of the equipment on it, which is quite different from the performance at power frequency. In this paper, based on numerical simulation, the factors due to the grounding grid that affect its transient performance were discussed. The methods to improve the transient performance of the grounding grid such as increasing the horizontal grounding conductors and vertical grounding conductors near the current injection point were presented. It shows that increasing the horizontal grounding conductors is such more effective than increasing vertical grounding conductors to decrease the ground potential rise and the potential difference in the grounding grid.
