Abstract
High voltage induction motor is the important equipment for ensuring the driving performance of the electric train. PD(partial discharge) is a good indicator for showing the insulation performance of stator coil in HV induction motor. This paper has investigated the characteristics of PD occurrence aspects for both the sound and defective stator coil which consist of maximum PD amplitude(V), total occurrence number, average PD amplitude(V) and PD amplitude(v) - PD occurrence number(n). They were compared with each other depending on applied voltages and reconstructed to
