| Abstract: | The effects of phase measuring errors on fault resistances of tree-type distribution line when line break with short-circuit have been investigated. The fault position is directly proper- tional to the deviation of phase measuring of fault line and two non-fault lines at the begining of the tree-type distribution line. According to the mathematical relationships, the real one can be distinguished from the false faults after the feature selection when the measuring errors exist. |
