Abstract

High speed train system consumes much electric power during running, and generate much EMI (electromagnetic interference) by arc between the pantograph and the trolley line. In this paper, EMI was measured following EN50121-2, 'Railway applications. - Electromagnetic compatibility. (Emission of the whole railway system to the outside world)', from the running high-speed railway (KTX) at 300 km/h speed. Measured results exceed the limit values of EN50121-2 in low frequency band ($9\;kHz{\sim}150\;kHz$), but they did not exceed the limit values in other higher frequency band ($150\;kHz{\sim}1\;GHz$).
