Polyimide nano-composite film (Kapton 100CR) is a special type of engineering plastic film, which is widely used in turn insulation of form-wound inverter-fed motor. Partial discharge (PD) caused by high-frequency surge impulse is one of the key factors leading to premature failure of turn insulation of inverter-fed motors. Aging experiments on turn insulation samples under repetitive bipolar square...
With the development of power electronics, Pulse Width Modulated (PWM) power has been applied widely. The pulse voltage engendered by PWM may lead to the premature failure of inverter-fed motors. Partial Discharge (PD) under a sequence of high-frequency pulse is one of the key factors which lead to premature failure of inverter-fed motors. In this paper, aging experiment on magnetic wires for turn...
