The transformer fault diagnosis model based on credibility

To rapidly and accurately define the level of the transformer fault and choose the appropriate occasion and scheme for eliminating fault, a transformer fault diagnosis model based on credibility is proposed. To the incomplete transformer fault symptoms, the model searches the match rule .and to incomplete transformer fault symptoms, the rough membership is used for determining the credibility of rules .So the model obtains the conclusion credibility while it obtains the conclusion. Practical applications show that for the incomplete transformer faults and the inference rule based on the experts' experiences, the inference conclusion with an additional credibility factor is obtained by using the model and the reliability for rapid defining default is improved.
