Vibration signature analysis of stator winding fault diagnosis in brushless synchronous generators

This paper studies the potential of using vibration signatures in detecting stator winding short-circuit faults in the brushless synchronous generator. The vibration data collected from the experimental setup under various degrees and severities of the stator winding short-circuit faults in the brushless synchronous generator are investigated to identify fault signatures in the vibration signal. Investigation on the vibration signals show that the fault signatures in vibration can be used to detect and diagnose the stator winding short circuit fault in the brushless synchronous generator. Besides this the identified fault signature can also be able to differentiate between the stator winding fault and load unbalance.
