ELECTRIC FIELD DISTRIBUTION AND SWITCHING IMPULSE DISCHARGE UNDER SHIELD BALL SURFACE SCRATCH DEFECT IN AN UHVDC HALL

The dimension and surface state of shielding fittings in ultra high voltage direct current (UHVDC) converter station valve halls have a great influence on their surface electric field and switching impulse characteristics, which are important parameters confirming the air gap distance in the valve hall.The characteristics of impulse discharge under

This contribution deals with the topic of the consistent further development of a wheel hub motor for battery electric vehicles (BEV) based on the principle of an outer rotor switched reluctance machine (SRM).The research work presented in this paper was founded by the ERDF.NRW program, Investment for Growth and Employment and the European Regional
