Power consumption evaluation standard which measured in 1996 is difficult to apply for the recent KORAIL electric train due to the change of train operating environment. This paper is compared with the power consumption by different ratio of power car and trailer car and train route characteristics. In order to measure the power consumption value, developed & installed electric power analysis equipment inside the Converter/inverter to record the electric power measured by voltage sensors and current sensors. Consumption of electric usage will be measured and analyzed until October 2010. We expect the measured power consumption value will be used for cost analysis as well as for the high efficient train system development.
