Moisture Content Analysis of Oil-Paper Insulation inTransformer and Its Inflence on Operation Safety
Liu Yu-xian · Transformer · 2002
The moisture-absorbing characteristics of oil-paper insulation under atmospheric condi-tion are discussed. The water vapour pressure and temperature curve used in vacuum drying oftransformer active part is given. The moisture equilibrium of oil-paper insulation in transformer isanalyzed. The factors to influence the transformer safety are summarized. The improving andpreventive measures are presented.
