Rotor inter-turn short circuit fault diagnosis based on the change of amplitude and phase angle
Wan Shu-tingb · Journal of North China Electric Power University · 2007
Firstly strained circumstances was analyzed when inter-turn short circuit fault happens in turbo generator,vibration expression was gotten under inter-turn short circuit state.By analysing the change of amplitude and phase angle during inter-turn short circuit,came to the conclusion of measuring amplitude and phase angle as inter-turn short circuit diagnosis method,and demonstrated its dependability.Finally simulated the transforming process of vibration phase angle,wave and amplitude,verification showed that the analysis is correct.
