Abstract
This paper quantitatively analyzes the impact of induced current and leakage current on GIL equipment by establishing a GIL shell circulating current calculation model. In addition, the GIL grounding system and shell circulation model were established. When the grounding spacing is less than 2000 m, the shell circulation and shell potential will increase significantly with the increase of grounding spacing, and the GIL shell potential shows a “U”-shaped distribution with low middle and high end. The potential can be reduced to a single digit to ensure the safety of staff.
