May 29, 2020After drying, with the drained transformer, dry air or nitrogen is applied to the transformer at minus 60°C dewpoint or dryer, and to a pressure of 2 psi. After 24 hours, the slightly pressurized dry gas is relieved through a dew point meter. If the transformer is dry, the dew point of the gas will have stayed around minus 50°C.
