| Abstract |
The increasing use of wideband gap devices poses a major challenge for the insulation system of motorwindings due to its steep dv/dt voltage slopes. This paper focuses on the application of a modular bipolarsquare-wave voltage generator, which was built at the Hochschule Hannover and is now used in thehigh-voltage lab. Exemplary measurement results related to qualification and condition monitoring arepresented. It is shown that the stress of a bipolar square-wave with high frequency and steep voltageslopes on the insulation system is much higher compared to a standard sinusoidal 50 Hz wave |
