틸팅열차 운행중 열차 진단을 위한 전기신호 계측 연구

It’s essential to measure electrical signals of Korea tilting train "Hanvit 200" during operation, Because we neep to study operation characteristics of new electric train "Hanvit 200" and we want to develop diagnosis system of main circuit of Korea tilting train "Hanvit 200". So, we measure electrical signals for developing diagnosis system of "Hanvit 200" during operation. We measure voltage and current of the primary winding of main transformer and analyze them. In result, we know that each operation has specific waveform and frequency. In addition, we also measure are currents and are voltage and we know that arc of each situations has specific waveform of pattern.
