Abstract :
The influence of logistics on the national economy increases as the economy advances. Vehicle transportation, however, cannot meet the ever-increasing transportation demand, with its economic efficiency deteriorating over time. Judging that such transportation demand cannot be met only by vehicle transportation, the government also seeks to increase transportation through railroads. In this study, the voltage supplied to train in trial operation was monitored and analyzed to identify the voltage condition supplied by the existing railroad. To directly measure the voltage supplied to train, PT was installed at the bottom of train pantograph for monitoring the primary voltage of the transformer, and for accurate measuring, surrounding environment and conditions were recorded and the analysis of stringing voltage using CBEMA curve was conducted. As a result, some of the section on Honam, Jonngang and Taebaek line were supplied 110[%] pf rated voltage (25[kV]) for more than 200[s] frequently exceeding 110[%] Taebaek line appeared to have had the installed voltage in worst condition.
