Abstract

The process of aging is attributed to many uncertain factors, and it was difficult to confirm the quantitative relations between the nondestructive parameters of insulation and the breakdown voltage. In this paper, by using mathematical method of fuzzy analysis the parameters are selected according to the correlativity coefficient between nondestructive parameters and breakdown voltage. Then the membership functions are decided and by using the verdict matrix method, each weight between nondestructive parameters and breakdown voltage is given. Finally a fuzzy model is established by those parameters obtained to evaluate the aging status by nondestructive parameters.
