Detection of Inter-turn Short-circuit Fault in Induction Motor Using Theory of Instantaneous Symmetrical Components

The use of electric motors in industry is extensive. These motors are exposed to a wide variety of environments and conditions, which age the motor and make it subject to inter-turn incipient faults. Stator winding is the heart of machine. Therefore, it is always essential to check winding performance from time to time. This can be done by various conventional methods are discussed here, and noninvasive approach, using the theory of instantaneous symmetrical component is introduced. The simulation and experimental results are reported to demonstrate the effectiveness of the proposed technique.
