摘要: Evaluations of partial discharge (PD) in 4160 V propulsion coils have been conducted to understand the impact inverter drives on electric motors as US Navy moves toward "electric" ship. The influence voltage level, rise-time, switching frequency and temperature generation PD for two different coil insulation systems was determined by optical electrical detection methods. This paper describes process characterizing conditions comprehensively based above four parameters, a drive system consisting an high torque, low speed motor. test setup is described well comprehensive results analyses.
