摘要：
The partial discharge (PD) characteristics of twisted pair samples for inverter-fed motor coil under AC and surge voltage conditions were studied. The PD inception voltage (PDIV) was measured and verified to agree well with the theoretical value using electric-field analysis and Paschen's law. The PDIV under surge voltage was measured for different repetition rates. It was found that the PDIV for 60-pps repetition was lower than those for 6 pps and for the single shot. The PDIV under surge voltages was 1.6 to 1.8 times and 2.3 to 2.7 times higher than those under AC voltage application for the used and virgin samples.
