Transformer dew point measurement insulation moisture 2 | TD

A calibrated dew point meter should always be used to perform the dew point measurement. The meter should be left in the same environment as the unit being tested for one to two hours to reach ambient temperature before use. Inspect the instrument condition prior to use. There should be a “zero” or calibrate process for the dew point meter.Get price

Moisture in Transformer Insulation

Dew Point Test After 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.Get price
