Railway applications - Supply voltages of traction systems

This European Standard specifies the main characteristics of the supply voltages of traction systems, *such as traction fixed installations, including auxiliary devices fed by the contact line, and rolling stock, for *use in the following applications : *– railways; *– guided mass transport systems such as tramways, elevated and underground railways mountain *railways, and trolleybus systems; *– material transportation systems. *This European Standard does not apply to *– mine traction systems in underground mines, *– cranes, transportable platforms and similar transportation equipment on rails, temporary structures *(e.g. exhibition structures) in so far as these are not supplied directly or via transformers from the *contact line system and are not endangered by the traction power supply system, *– suspended cable cars, *– funicular railways. *This European Standard deals with long term overvoltages as shown in the Annex A.
