Nettet25. apr. 2024 · This paper proposes a new method using Artificial Neural Network (ANN) for detection of different Inter Turn Short Circuit (ITSC) faults in an induction motor under different loading conditions. NettetWhen a turn-to-turn short fault occurs in an induction motor, it will be accompanied by vibration and heating, which will have adverse effects on the entire power system. Thus, turn-to-turn short fault diagnosis of the stator is required, and major accidents can be prevented if an inter-turn short circuit (ITSC), which is the early stage of a turn-to-turn …

NettetThe turn-to-turn SC (TTSC) fault is inherently self-exacerbating and for the TTSC of a stator winding there are lowest voltage and the highest current in the SC fault turns. Since the ohmic losses are directly proportional to the square of the current, the generated heat may damage insulation of the adjacent SC turns and the fault spreads to more turns.
