IEC 62590/FRAGF ED2

Railway applications - Fixed installations - Electronic power converters for substations

Scope

This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Incorporation of DC converters.
b) Correction of the clearances and withstand voltages due to erroneous use of PD in former edition.
c) Adaption to current ISO/IEC directive part 2, adaption of structure, adaption of vocabulary, removal of unused term and abbreviations.

This document 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 document applies to fixed installations of the following electric traction systems:
• railways,
• guided mass transport systems such as: tramways, light rail systems, elevated and underground railways, mountain railways, trolleybusses.
This document does not apply to:
• cranes, transportable platforms and similar transportation equipment on rails,
• suspended cable cars,
• funicular railways.

This document applies to diode rectifiers, controlled rectifiers, DC converters, inverters and frequency converters.
The equipment covered in this document is the converter itself.
