| Abstract: | Based on the overview of the principle of single|phase|to|ground fault protection for small current neutral grounding at home and abroad, this paper analyzes the advantages and disadvantages of principles for all kinds of single|phase|to|ground fault protection being used currently. A new principle based on active component direction of zero|sequence current is put forward. At the same time, the action parameters of selective grounding fault protection device are presented. |
