| Abstract: |
| By analysising the zero sequence transient current and zero sequence total current during single phase grounding fault in power system whose neutral point does not connect to the ground, the limitation of using zero sequence transient current line selection and the question which should be noted when using zero sequence elementary wave current line selection are pointed out. |
| Key words: transient current,elementary wave current,breakdown line selection |
