Influence of discrete series devices on crosstalk phenomena in multiconductor transmission lines

Abstract

Usually the crosstalk mechanisms in multiconductor transmission lines (MTL) are studied considering lumped loads or devices connected at the line terminations (either at source or load ends) or as shunt load to ground along the lines, as seen in conventional power and railway system networks. However there are practical systems, e.g. like in typical Swedish railway systems, wherein discrete lumped devices like the booster transformer (BT) exist in series with the line. With lightning transients various parameters that influence crosstalk in MTL systems, such as the ground conductivity, have been analyzed e.g. in [1]. For realistic crosstalk analysis we conclude that inclusion of discrete devices like BT should be accounted. The study could be beneficial in better understanding of the crosstalk mechanism in the electrified railway systems.
