This International Standard specifies the requirements for the performance of all fixed
installations electronic power converters, using controllable and/or non-controllable electronic
valves, intended for traction power supply.
The devices can be controlled by means of current, voltage or light. Non-bistable devices are
assumed to be operated in the switched mode.
This Standard applies to fixed installations of following electric traction systems:
– railways,
– guided mass transport systems such as: tramways, light rail systems, elevated and
underground railways, mountain railways, trolleybusses.
This Standard does not apply to
– cranes, transportable platforms and similar transportation equipment on rails,
– suspended cable cars,
– funicular railways.
This Standard applies to diode rectifiers, controlled rectifiers, inverters and frequency
converters.
The equipment covered in this Standard is the converter itself.
