Modelling of breakdown voltage of white minilex paper in the presence of voids under AC and DC conditions using fuzzy logic techniques

Abstract

Gaseous cavities present in the insulation materials can lead to continuous deterioration and eventually breakdown of insulation materials. To determine the stability of use and to acquire the data for the modeling and designing of electrical insulation systems ,breakdown voltage (BDV) of the insulation should be determined. In this paper, Fuzzy Logic (FL) method is used to model breakdown voltages of White minilex paper samples based on experimental data generated in the laboratory. Different models are proposed with different membership functions for the FL under both dc and ac voltage conditions. The cavities are created artificially. Low values of mean absolute errors of the estimated breakdown voltage of the test data show the efficiency of the models.
