PD Characteristics of inverter-fed AC motor subjected to impulse voltage in electric train

전동차내 임펄스 전압인가에 따른 인버터구동형 유도전동기의 PD 특성

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.
