In this paper, a high-voltage circuit breaker diagnosis method based on gray correlation analysis and DS evidence theory is proposed for the fault diagnosis of high-voltage circuit breakers. The fault diagnosis calculation results of a high voltage circuit breaks using this method are compared with those using only gray correlation analysis. The comparison result shows that the proposed method has higher accuracy and reliability, and can accurately determine the type of faults occurring in the high-voltage circuit breaker through the monitored characteristic parameters, avoiding more subjective judgments and improving the reliability of the results.
