Abstract: A method and arrangement for pressing of windings assembled onto a transformer. The method includes applying pressing force on the windings, and controlling the pressing force on the windings during drying of transformer active part. Thus, before the drying process commences, the windings are assembled onto the transformer core and a pressing force is applied to the windings assembled onto a respective transformer core limb, wherein an individual pressing force is applied to the respective winding. This individual pressing force applied to the respective winding is then controlled during the process of drying the transformer active part. The windings will as a result advantageously be effectively compressed onto the core and stabilized.
