Abstract :
Technically and economically optimized insulation systems can only be offered today if there is complete knowledge of phenomena in the winding insulation that determine its service life. This paper describes how such mechanisms are influenced by operating conditions, how they are detected using modern diagnosis methods, and how they can be intentionally influenced by the design of the insulation.
