In the manufacturing process of a transformer, the drying operation of the active parts is an essential activity for the final quality of the transformer. Composed of moisture-absorbing materials, the isolating quality of these ones is polluted by the present water and is incompatible with the notion of dielectric. In order to remove this moisture, the manufacturers resort to an operation of atmospheric drying, through warm air ventilation or under vacuum to speed up the phenomenon of water vaporization.
