  Abstract

Most domestic and high-speed railway lines are equipped with AF non-insulated track circuits, which can lead to system malfunctions and faults if unbalanced or over-current conditions occur. The load current due to the power converter inside the train contains harmonics and these harmonics can affect trains as well as the transmission of track circuit data in substations and signaling systems. If the train control system malfunctions due to the inability to receive data from the track circuit due to the influence of the return current harmonic, it may cause problems such as interruption of train operation. Therefore, an accurate analysis of the return current is needed to prevent the return current unbalance and the system induced disorder and failure due to an over current condition. In this paper, we presented measurement and analysis method at return current and it"s harmonics by high speed train operation on the honam high speed line.
