外文摘要：An early diagnosis of faults prevents financial losses and downtime in the industry. In this paper, the authors present the early fault diagnostic technique of inter-turn short-circuit fault in induction motors, so the Park's Vector Difference Approach (PVDA) is introduced. The fault current vector ring subtracts the three current vector ring of normal operation at a certain voltage to get a petal. Thus, the amplitude of 3 Hz components of the petal with the Fast Fourier transform (FFT) is the characteristic quantity of the fault motor, through which stator winding fault is detected as well as the degree of the stator winding fault. Experiments were performed at different loads and unbalanced voltage. Efficiency of the proposed method is validated experimentally on a 0.1 kW motor. The results are proved to coincide satisfying, whereas the proposed advanced Park's Vector Difference Approach method is desirably reliable. ? 2021 IEEE.
