Abstract
Recently, the Korea Tilting Express(TTX), "HANVIT 200", KRRI(Korea Railroad Research Institute) developed runs for test on the conventional railroad, Honam line, Center line, Chunk-buk line and Tae-baek line. In this paper, we measured the service voltage while TTX ran on the conventional railroad and analyzed the condition of voltage. For measuring voltage directly, we installed PT under the pantograph and measured the voltage of the primary winding. In addition, we record situations that other trains pass by TTX and environments while TTX ran. And then we analyzed the condition of voltage using the records and CBEMA curve. In result, over 110[%] voltage of rated voltage(25[kV]) often occurred and the voltage of some place continued over 110[%] for about 200[s]. Especially, the voltage condition of Tae-baek line is the worst. The results in this paper can help to stabilize the power device and power converter of TTX.
