Aging assessment method of oil–paper composite insulation based on repeated polarization current characteristics

Abstract To explore the aging assessment method of the oil–paper insulation in power transformers, the polarization and depolarization current (PDC) characteristics of oil–paper composite insulation samples are investigated under high applied voltage. Based on the asymmetry of polarization absorptio...
