Abstract:
In order to make the evaluation index weight more reasonable，and achieve the reasonable predic-tion of the remaining life of the power transformers, this paper used three - scale method to construct judgmentmatrix , and combined the line normalization method with eigenvector method to achieve the improvement of thefuzzy analytic hierarchy process.This method is applied to the transformer remaining life assessment model,has improved the objectivity and rationality of the judgment matrix，and enriches the basis for this assessment,the results of the assessment are more accurate and have the practical guiding significance.
