[4F4-GS-10o-01] Investigation of the Life Estimation for the Deterioration by Void Discharge in Epoxy Resins Using Machine Learning
Keywords:Void Discharge, Degradation estimation, Support Vector Machine
In addition, the generation distribution in the AC voltage phase of partial discharge correlates with the discharge generation factor, so it is used as an index for maintenance.
This time, we focused on the void discharge deterioration in the epoxy resin, which is a factor of aging deterioration, and investigated whether the degree of deterioration can be estimated by learning the phase characteristics of partial discharge generation using various machine learning methods.
In order to estimate the degree of deterioration from the partial discharge, what is used as the feature quantity from the partial discharge pattern is important.
In this study, the maximum absolute value of the partial discharge voltage and the average absolute value of the partial discharge voltage that can be obtained from the partial discharge pattern were used as the characteristic quantities of the partial discharge used for estimating the degree of deterioration.
Using these features, we estimated the degree of deterioration by applying multiple machine learning methods including support vector machines.
As a result, it was shown that the degree of deterioration can be estimated at about 85\% in the support vector machine.
