On thebasis ofthepercolation modelfor electrical breakdown ininsulating polymers, asimulation approach wasputforward fortheprocess ofelectrical aging. Thedeteriorated regions formed bybondscission areexpressed asthesites withlower trapbarriers, and thelocal deterioration rate isrelated toboththeelectrical field andthesize ofexisting deteriorated regions. Then thereduction ofbreakdown strength (orthepercolation threshold) withtheincrease ofdeteriorated sites canbe simulated. Assuming aparameter… CONTINUE READING
