Abstract

High speed train system generates much EMI (electromagnetic interference) by arc between the pantograph and the trolley line during the running time. EMI from the tilted EMU train system which is similar to HEMU-400X system for 400 km/h speed and with the distributed engines was measured following EN50121-2, 'Railway applications. - Electromagnetic compatibility (Emission of the whole railway system to the outside world)'. Measured EMI values exceed the limiting values of EN50121-2 in high frequency band ($30\;MHz{\sim}1,000\;MHz$), but exceeding frequencies were identified that they are used for mobile communications. Measured EMI values did not exceed the limiting values in other low frequency band between 9 kHz and 30 MHz.
