초록

AC induction motor equipped in electric train is driven by VVVF inverter which produces switching pulse like impuse. Impulse voltage is more dangerous than continuous alternative voltage for the insulating performance of AC induction motor. This paper has investigated PD characteristics caused by impuse voltage for stator coils inserted in AC induction motor.
