The stator inter-turn faults and stator electrical asymmetries such as stator resistance and inductance unbalance generate similar negative sequence current signatures in the induction machine. Hence the stator inter-turn fault is one of the most difficult faults to discriminate and detect in an induction machine. Discrimination of the stator inter-turn fault from stator electrical asymmetry essentially...
Conventional models of induction machine for steady-state and dynamic analysis use fixed value of the rotor resistance; whereas for representing the deep-rotor-bar effect a second rotor branch is typically required therefore increasing the model complexity and order. This paper proposes a simple but very effective modification of traditional model, wherein a single-branch rotor resistance is changed...
