Abstract:Oil-paper insulation plays an important role in the internal insulation of power transformers.Aging of transformer insulation is a gradual procedure which can eventually threaten the safe operation of power transformers. During long-term operation of power transformers, oil-paper insulation is exposed to multiple stresses, including electrical, thermal, mechanical factors and so on. Lot of vigor is given to maintenance of the health of transformers in transmission system. Usually the reliability of power trans… Show more
