In this paper, while electric multiple unit is moving on the rail, the content of measuring and analysing electric power consumption is mentioned. In order to measure the electric power consumption, we developed the power record analysis equipment and installed it the inside of the converter and inverter system to record the electric power consumption measured by voltage sensor and current sensor. Moving on the rail, we analysed traction power used up and regenerative power by using the measuring instrument. We expect that the measured and analysed data will offer basic research material to devise a energy reduction plan and introduce a new EMU system with high efficiency.

In this study By the time that TTX technology is adopted as railway rolling stock we analyzed quantitatively energy saving by reducing the power consumption with the reduction of the operation time through the speed improvement and suggested the necessity to introduce TTX technology in the domestic rail vehicles. The effect of energy saving by comparing and analyzing the power consumption during the operation by TTX Hanvit 200 and 8200 electric locomotives to pull trains on the same line was suggested and the efficiency of the main devices(i.e C/I) of Hanvit 200 was compared and analyzed by measuring the power consumption by a single unit. For improving KORAIL management environment reducing energy usage is an urgent challenge its measures for solving them are constantly considered in many areas. In addition at the time of improving the conventional track to speed up and changing the signals Tilting technology will be contributed to the management environment by enlarging the passengers' demand through the reduction of the operation time and saving energy using the existing infrastructure.
