| Abstract: | A new method for fault diagnosis of tank electric starting system was put forward based on the non-stationary characteristics of starting current.With the wavelet singularity detection theory,the singular points of starting current were analyzed and identified.The tank practical application shows that the proposed method based on wavelet singularity analysis can effectively extract the key characteristics of starting current and realize the identification of obvious and hidden faults of electric starting sy... |
