Inter turn Fault Analysis on Wound Rotor Induction Machine

Abstract

Abstract Prevention of industrial machineries against internal and external faults is mandatory for uninterrupted operation. Identifying the exact faults or anomalies in the system and predicting the machine’s health continuously is an essential preventive measure. To realize the protection system, pre-analysis of various faults under different load conditions is mandatory and hence, paper analysis a critical fault “Inter turn fault” in the wound rotor induction machine (WRIM). Inter turn fault is developed experimentally in 2.2 kW WRIM with 20 percent of internal windings shorted under different load conditions (0 to 1 per unit load). Obtained results are analysed for various electrical and mechanical parameters, and the faulty effects are revealed.
