It follows the winding journeys of four people who turn to plastic surgery as the lastresort in their search for perfection.

Based on the analysis of AC impedance and two poles voltage test data, the reason of turn - to - turn short circuit fault caused by having copper dregs in generator rotor winding was found.

Experimental results demonstrated that the spectrum characteristics based on coherence analysis can be used to diagnose the stator winding inter-turn faults of induction motors.
