filteration?
Answer Posted / k.prakashchandra
To dehydrate the windings.In view of high level of water /
moisture content in insulation ,it is recommended to
thoroughly dehydrate the windings by subjecting to vacuum
heating and drying after untanking the oil.Care should be
taken to see that the tank would not buckle due to the vacuum.
