| Abstract: | The defects of stator insulation layer are the main causes of electric machine fault.The detection model of induction motor can examine a few short circuit faults of windings.Analyzing the phase current by using Kalman filter,the truth has been verified that tiny short circuit current can be identified,so as to the effective measures can be applied to avoid the happening of accident. |
