The effect of oil contaminated environment in oil-cooled inverter-fed motor on the partial discharge inception voltage (PDIV) of aramid papers with different thickness was studied at different temperatures using a ball-plate electrode configuration. The results show that the PDIV of aramid papers increases with the increase of thickness and is greatly affected by temperature. With the continuous increase of temperature, the PDIV decreases to a great extent. Cooling oil can significantly increase the PDIV at room temperature, but at high temperature, the PDIV will reduce, which may affect the insulation properties of aramid papers. Therefore, in order to improve the electrical properties of insulation system when aramid paper is used as the main insulation in inverter-fed motor, the above characteristics need to be considered.
