| Abstract: | The propagation of vibration wave creaeed during circuit breaker operation is researched . The method which uses the phase - frequency characteristic to describe the propagation of vibration wave is pro- posed . Through the analysis to the phase - frequency characteristic of the analytical signal of vibration sig- nal, a way distinguishing the different vibration events aliasing in time domain is given . |
