| Abstract: |
| Based on wavelet transform ,a novel on-line detection method is presented ,which is based on the detection of symmetry degree among the stator three-phase line currents phases.The analysis shows that it has excellent sensitivity ,and can produce stable computational results and detect the inter-turn short-circuit faults accurately.This project is sponsored by National Natural Science Fund of China ( 50077008 ) and Natural Science Fund of Guangdong ( 980608 ) . |
