According to intelligent complementary ideas, a new transformer fault diagnosis method is proposed based on rough set (RS) and Bayesian optimal classifier in this paper. Through RS reduction, the diagnostic decision table is simplified and fault symptoms information is compressed, and the minimal decision rules can be obtained. In light of the minimal decision rules, the complexity of Bayesian reasoning and difficulties of fault symptom acquisition are dramatically decreased. Moreover, probability reasoning may be realized by applying Bayesian optimal classifier, which can be used to describe the characteristics of fault information and investigate the fault reasons of transformer. In the end, a simulation example in transformer fault diagnosis indicates that the method is very effective and ubiquitous.
