The method serves for drying an active part containing at least one winding and solid insulations. The active part is arranged in a vacuum-tight housing and is heated there to a final temperature value (Tfin) by means of warmed oil and by means of a current (I) carried in the winding. The warmed oil is sprayed in the housing at reduced pressure (p) and with the current (I) switched on. At the same time, water is extracted from the active part. The sprayed oil is collected on the housing bottom, after discharging heat to the active part, and, after rewarming, is sprayed once again in the housing at reduced pressure and with the current switched on. The active part is thus dried particularly quickly and carefully. |
