抄録
Short-circuit faults of winding due to the deterioration in the insulation is one of the most probable faults in motor drive systems. An easy and effective fault diagnosis method has been strongly required to assure operation with high reliability. This paper proposes a novel method for diagnosing both short-circuit faults and insulation deterioration in windings. This method involves an impulse voltage test and probabilistic process for gauging the probability of fault occurrence by considering the distributions of features depending on the condition of the winding. In this paper, first, we discuss the results of several impulse tests on the winding. Second, two features that represent the characteristics corresponding to the condition of the winding are induced, and their feature distributions are determined. Third, we introduce the probability that can be used to diagnose the condition of the winding. The average and standard deviation of both features are calculated. By using the calculated values and features observed in a target winding to be examined, the fault probability is computed. Finally, the usefulness of the proposed diagnosis method is verified by performing experiments involving the use of faulty and deteriorated windings.
