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



Reference EN 50388:2005
Title Railway applications - Power supply and rolling stock - Technical criteria for the coordination between power supply (substation) and rolling stock to achieve interoperability
Project Number 12125
Abstract/Scope This European Standard is intended to be used to set up the requirements for the acceptance of rolling stock on infrastructure in the field of: - co-ordination of protection principles between power supply and traction units, especially fault discrimination for short-circuits; - co-ordination of installed power on the line and power demand of the trains; - co-ordination of traction unit regenerative braking and power supply receptivity; - co-ordination of harmonic behaviour. This standard deals with the definition and quality requirements of the power supply at the interface between traction unit and fixed installations. The standard specifies the interface between rolling stock and electrical fixed installations for traction, in the frame ”supply system“. The interaction between pantograph and overhead line is dealt with in EN 50367. The interaction with subsystem “control-command” (especially signalling) is not dealt with in the standard. Requirements are given for the following categories of line: - TSI lines (high speed and conventional), - classical lines. For classical lines, values, if any, are given for the existing European networks. A set of values is also specified for the future network, which is named ”target“ network. The following electric traction systems are concerned: - railways; - guided mass transport systems that are integrated with the railways; - material transport systems that are integrated with the railways. This standard does not apply retrospectively to rolling stock already accepted by infrastructure managers. However, on new infrastructure, existing rolling stock may be accepted by the infrastructure manager, provided there is an agreement. Information is given to the train operating companies on electrification parameters to enable them to confirm after consultation with the rolling stock manufacturers that there will be no consequential disturbance on the electrification system.

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.
