Effects of shorter phase-resolved partial discharge duration on PD classification accuracy
International Journal of Power Electronics and Drive Systems (IJPEDS), 2020 <span>Partial discharge (PD) pattern recognition is useful to diagnose insulation condition. PD measurement data is commonly represented in phase-resolved partial discharge (PRPD) format. PRPD is useful as it provides a visible pattern for different PD source and various features can be extracted for PD pattern recognition.
