| Abstract: | The transmission line damage is mostly caused by short-circuited fault.The short-circuited fault is analyzed and then the fault current is detected using lifting wavelet.The simulation results show that lifting wavelet effectively detects the signal singularity of transmission line short-circuited fault.Compared with traditional wavelet transform,lifting wavelet transform calculates fast and easily. |
| Keywords: | lifting wavelet transmission line short-circuited fault detection |
