Abstract

Estimating the interference current produced by railcars is necessary to ensure electromagnetic compatibility (EMC) between railway signaling systems and railcars. Although various types of signaling systems use low-frequencies such as those used for track circuits, no estimation method so far covers low-frequency return-currents on DC electric railcars. This paper proposes a new method for estimating the spectrum of low-frequency return-currents on DC electric railcars. This method only requires DC electric railcar characteristics such as train mass and starting acceleration. Measurement results presented in this paper clearly indicate the effectiveness of the developed method.
