Trackside Power Transformer

Trackside Power Transformers are used for stepping down the voltage levels for the railway network. They are used to provide single phase supplies for train overhead systems. The duty of traction supplies transformers is a particularly difficult one, as overloading up to twice full-load current can appear. Furthermore, trackside transformers need to withstand system short-circuits which may be as high as 250 per year of varying magnitude up to full fault current. Height of the unit is reduced by mounting the active part horizontally.
