Abstract

To promote mechanical fault diagnosis efficiency and accuracy of high voltage circuit breaker

a novelfault diagnosis approach based on Relief F algorithm and gray relation analysis（GRA）method is presented in thispaper. Firstly

20 different features are extracted from opening/closing coil current curves and Relief-F algorithm isapplied to determine the weight value of each feature. Then

the fault samples composed of critical features are usedto establish the reference sequences and the corresponding weights of features are normalized. Finally

relation de-grees between reference sequences and testing sequences are calculated to determine fault types of circuit breaker.The testing results indicate that the proposed method can diagnose mechanical fault accurately

and the applicationof Relief F reduces complexity of fault diagnosis model and increase fault diagnosis efficiency

which suggests apromising application prospect.
