Although of relatively low power, these elements are 501211 to the line and may affect other railway apparatus. It is the constant aim of BSI to improve the quality of our products and services.

Your basket is empty. This publication does not purport to include all the necessary provisions of a contract. The Electronic Components EMC department of the ANPI laboratories conducts tests on components installed on trains and along the tracks, in accordance with the following standards. This plan should be established at as early a stage of eb project as is possible. This European Standard supersedes EN An overhead line can act as an antenna; auxiliary apparatus on traction vehicles may have relatively high power rating and must be considered as a source 501211-1 noise; the sliding contact between the line and the pantograph or shoe and rail.

It defines the applied test methods and gives information on typical field strength values at traction and radio frequency cartography. Electromagnetic compatibility Rolling stock.

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.


It supersedes BS EN 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 within diesel-electric locomotives and multiple units; battery traction vehicles.

The variety and the diversity of the apparatus within the scope of this set of standards makes it difficult to define precise criteria for the evaluation of the immunity test results. Customers who bought this product also bought BS EN Five modes of coupling are distinguished: If you need help with the purchase or have any e please email enquiries standards.

The immunity levels for the apparatus will normally ensure reliable operation, but it is necessary to prepare an EMC management plan to deal with complex situations or to deal with specific circumstances. Information regarding online access to British Standards via British Standards Online can be found at http: Railway overhead systems differ from most high voltage overhead lines by being closer to the ground, having more insulators and having less natural cleaning of the insulators.
