Among the phenomena which are involved een RF emission are: Such locomotives also contain auxiliary systems which may be sources. The market for on-board electrical equipment on trains and for signalling equipment installed alongside the tracks is especially demanding because of: Supersedes BS EN On the traction vehicle, the power is regulated and supplied to electric motors to control the movement of the train. The normal and disturbed working of these systems may be a source of electromagnetic noise which can affect all other systems.

Although of relatively low power, these elements are close to the line and may affect other railway apparatus. The apparatus shall continue 05121-1 operate as intended during and after the test. Revisions British Standards are updated 50211-1 amendment or revision. If, as a result of the application of the tests defined in this set of standards, the apparatus becomes dangerous or unsafe, the apparatus shall be deemed to have failed the test.

Emission of the whole railway system to the outside world Railway applications – Electromagnetic compatibility Part The standard cannot cover all the 50112-1 configurations of apparatus, but the test levels are sufficient to achieve satisfactory EMC in the majority of cases.

The railway is an integrated system in which electricity has 50121–1 uses in addition to train propulsion including: It is the constant aim of BSI to improve the quality of our products and services.

Emission limits at the railway boundary do not apply to intentional transmitters within the railway boundaries. A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions.


Emission and immunity of fixed power supply installations and apparatus This part applies to emission and immunity 501211-1 of EMC for electrical and electronic apparatus and components intended for use in railway fixed installations associated with power supply.

Railway applications – Electromagnetic compatibility – Part 1: General

It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used.

We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover. Standards are also available from the BSI website at http: Limits are also placed on EM emission by railways into the outside world.

Annex A describes the characteristics of the railway system which affect electromagnetic compatibility EMC behaviour. Emission and immunity of fixed power supply installations and apparatus EN EN EN EN EN 2 Normative references The following referenced documents are indispensable for the application of this document. An overhead line can act as an antenna; auxiliary apparatus on traction vehicles may have relatively high power rating and must enn considered as a source of noise; the sliding contact between the line and the pantograph or shoe and rail.

The scope of this part of the Standard ends at the interface of the stock with its respective energy inputs and outputs. Throughout the set of standards, the immunity levels are chosen to ensure a reasonable level of EMC with other apparatus within the local railway environment and with emissions which enter the railway from the outside world.

The performance level may be replaced by a permissible loss of performance. Apparatus BS EN Electrical noise may energise the detector although the train is present, giving a false indication of clear track.

Electromagnetic compatibility Emission and immunity of the signalling and telecommunications apparatus BS EN The traction and auxiliary equipment on the vehicle and the substations shall not generate currents at track circuit frequencies which exceed specified values. Compliance with this standard provides one means of conformity with the specified essential requirements of the Directive concerned.

This power is fed along the train by separate conductors; signalling and telecommunication systems along the track and between control centres, concerned with the movement of trains; computer installations in control centres, linked via trackside routes; passenger information systems on vehicles, stations and depots; traction 5012-1 diesel-electric locomotives and multiple units; battery traction vehicles.

When a train travels on the track, its axles short-circuit a detector of this electrical supply and the presence of the train is detected. Radio frequency radiated waves.

Isolated three phase lines exist with two overhead conductors. Information regarding online access to British Standards via British Standards Online can be found at http: It is not, therefore, possible to establish immunity tests and limits for these large assemblies.

These effects are entirely internal to the railway and many different cases can exist. It defines 501221-1 applied test methods and gives information on typical field strength values at traction and radio frequency cartography.

Rolling stock – Apparatus Een applications 50112-1 Electromagnetic compatibility Part 4: The immunity and emission levels do not of themselves guarantee that integration of the apparatus within the railway will necessarily be satisfactory.

During the test, degradation of performance is however allowed. The frequency covered by the standards is in the range from d. Worldwide Standards We can source any standard from anywhere in the world.
