| Abstract | ||||
| The use of induction 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 faults. One major cause of these faults is breakdown of the turn insulation leading to damage the ground insulation wall. Early detection of inter turn shorts during motor operation would eliminate consequential damage to adjacent coils and the stator core reducing repair costs and motor outage time. This paper deals a modeling simulation and detection of induction motor inter turn short circuit faults. A new detection method for inter-turn short circuit faults in stator windings using sum of stator currents was presented. The simulation and experimental results are reported to demonstrate the effectiveness of the proposed technique. | ||||
