Analytical Investigation of the Humidity Effects on Repetitive Partial Discharge Inception Voltage in Inverter-Fed Motor Windings
Inverter-fed motors are exposed to high dv/dt surge voltages that can initiate partial discharge (PD) in winding insulation, particularly under humid operating conditions. This study examines the effects of humidity on the repetitive PD inception voltage (RPDIV) using twisted-pair samples and a SiC-MOSFET-based pulse p...
