International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference CLC/TS 50546:2013
Title Railway applications - Rolling stock - 3-phase shore (external) supply system for rail vehicles
Project Number 21417
Abstract/Scope This Technical Specification provides the requirements for compatibility of systems defined and good practice for three phase AC 400 V/50 Hz shore (external) supply systems. It focuses on describing the defined interfaces regarding electrical power supply in stations, depots/workshops and stabling points into the rail vehicle. This Technical Specification provides recommended characteristics of power supply and its connectors. The electrical characteristics relate to 3 AC 400 V/50 Hz. Sensing of phase rotation is outside the scope of this standard but it is assumed that phase sequence between the external supply and the railway vehicle is synchronised. Annexes have been provided for National Systems, using three phase 400 volt / 50 Hertz shore supply systems, where full information is available.

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
