Instructions - Electrical Engineering Portal· PDF fileA dew point measurement of the gas inside the transformer tank can be used to estimate dryness of the insulation system. Using this technique, it is assumed that moisture content of the gas is in equilibrium with the moisture content at the surface of the insulation material. The dew point test should be performed as described below.
