Once moisture enters a transformer, it is quickly absorbed by the cellulose (paper). 99% of moisture in a transformer will be found in the cellulose with the remaining 1% in the oil. Drying cellulose without completely removing the transformer oil can take months to years and is very difficult to do. Increasing moisture content in a transformerGet price
