Partial discharges (PD) are influencing electrical insulating systems of high voltage electrical devices. Typically, in laboratory and diagnostics AC tests focused on measuring and analysis of PD, a pure sinusoidal voltage waveform is assumed. Howeve

Power electronics switching devices currently represent the dominant technology for supplying low voltage (LV) electric motors. The fast switching processes exert a different class of stress on dielectric insulating materials than standard sinusoidal

This paper describes a novel approach to understanding partial discharge (PD) dynamics and mapping of the discharge channels in a void. During long term PD exposure, discharges develop inside channels within a void, leading to a variation in the disc

This paper describes a novel approach to investigating the mechanisms related to partial discharge dynamics. Applying the chopped sequence provided insight into the dielectric void and allowed post partial discharge charge decay phenomena to be inves

This paper presents comparison of effective discharge area in voids in different insulating materials based on surface resistance. Effective discharge area is defining spots where partial discharges are likely to occur. The changes of surface resista

This paper describes a new and intriguing observation relating to partial discharges specifically those discharges which occur despite the absence of an applied voltage within chopped sequence. The discharge pulses, which are referred to as Partial D
