This paper expounds that choosing the neutral grounding method for power grids is a comprehensive issue.It analyzes the calculation of single-phase grounded capacitor current and the selection calculation of neutral point equipment.Although the grounding fault current is selected as 1 300A,it is calculated that the step voltage and contact voltage can meet the requirements of the regulations and specifications.
