In this paper, measuring equipment for arcs which are caused by losing contact between a pantograph and a catenary in the electric train, TTX, was designed and we actually measured arcs of current and voltage at 2007. 5. 16 ~ 17, 2007. 5. 31, 2007. 6. 18 - 19 and 2007. 6. 30 ~ 31, a total of 4 times. The FFT tool was made by LabVIEW software and the actually measured arc data were analyzed by the FFT tool. The analysis result showed that the arc current and voltage contains much harmonic, so we must consider problems of EMS and EMI in the main circuit system of the electric train, TTX.

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.

Recently, the growth of electric railway system technology steadily keeps up in the Korea, and occupancy rate of electric railway system is increased as a transportation method. So, energy consumption of railway system is increasing. According to this reason, the many study of energy efficiency in the railway system are in progress. In this context, electric railway needs to measure and analyze electric power as drive states. And, drive states are classified into coasting state, acceleration state, and regenerative breaking state This paper focus on regenerative breaking state, and we descant through measured data of test driving of Tilting Train express

According to this reason, the many studys of energy consumption in the railway system are in progress. In this context, the TTX(Tilting Train eXpress) needs to measure and analyze energy consumption and regenerative energy. In this paper, because of driving of TTX in the Ho-Nam railroad and Jung-Ang railroad, consumpted and regenerated energy are measured. This measured data is classified and analyzed as driving mode.

Recently, TTX(Tilting Train eXpress), EMU(Electric Multiple Unit) has operated test. Presently, electric problems(harmonic, voltage variation etc) of TTX are studying briskly. Henceforth, electrical harmonic study of TTX will operate on the rail actually is needed. In this paper, we detected electrical harmonic of operating TTX. In addition to we analyzed and estimated electrical harmonic regarding TTX's coasting, acceleration and braking state.

Recently, TTX(Tilting Train eXpress) has operated test. Electric railways, including the TTX, have electric problems(harmonic etc) that could bring about serious accidents.. Thus, TTX's electrical problems also need leading studies because the new Korean TTX will operate earnestly in 2012. In this paper, electrical signals in TTX operation were detected to analyze electrical harmonic. The electrical harmonics considered operation modes triparted(coasting, acceleration, braking) were analysed and evaluated.

Recently, the new Korean Tilting Train Express(TTX) which maintains a speed on the curve railway line is developed. Electric railways, including the TTX, have electrical problems that could bring about serious accidents. For such reasons, the electric railway's electrical problems, electrical harmonic and others, have been studied briskly. Thus, TTX's electrical problems also need leading studies because the new Korean TTX will operate earnestly in 2012. The results could be used hereafter diagnosis of it's components and train conditions. In the paper, electrical signals in TTX operation were measured to analyze electrical harmonic. In addition, after the electrical signals were measured to operating mode (coasting mode, acceleration mode and regenerative breaking mode) respectively in test section(Ho-nam line, Chung-buk line, Jung-ang line and Tae-baek line). The electrical harmonics considered operating modes triparted were analysed and evaluated.
