| Abstract |
Due to the high voltage slopes from the wide bandgap (WBG) power electronics, which generate highfrequency (HF) electromagnetic noises, the identification of partial discharges (PD) becomes very cumbersome. In this paper, a validated PD detection system is utilized to decouple PD signals from those HF noises. In addition, the influences of different insulation systems, grade of insulated wires, steepness of the voltage slope as well as voltage overshoot because of various cable length on the PD events are also presented. |
