Round-robin test of repetitive partial discharge inception voltage measurements on complete winding of 4 kW random-wound motor

摘要

Measurements of repetitive partial discharge inception voltage (RPDIV) based on IEC 60034-18-41 using a stator coil winding of 4 kW random-wound motor have been performed in round-robin test (RRT) in Japan. A commercially available impulse power supply and a PD sensor were commonly used in the RRT. The present paper reports not only test procedure and results of RRT but also additional experimental data to clarify the mechanism of PD phenomena in the RRT.
