20、upersedes EN 50152-3-3:2001. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CENELEC shall not be held responsible for identifying any or all such patent rights. This standard was revised to reflect the latest versions of standard

21、s referenced and to remove text already included in the EN 61869 Series. The structure of the document was adapted to that of EN 50152-1 and EN 50152-2. Ratings have been added to provide designations in line with other railway standards e.g. EN 50124. Tests requirements have been detailed to meet o

22、perating conditions of railway applications. Partial discharge voltages have been specified in Table 2. This standard has to be read in conjunction with EN 61869-1:2009 and EN 61869-3:2011. Where a particular clause/subclause of EN 61869-3 is not mentioned in this standard, that clause/subclause app

23、lies as far as reasonable. Where requirements relate exclusively to three-phase systems or to voltages outside those in use in traction systems, they are not applicable. Where this standard states “addition” or “replacement”, the relevant text of EN 61869-3 is to be adapted accordingly. The numberin

24、g of clauses in EN 61869 Series is similar to that in the EN 50152 Series. Where terms defined in EN 61869-1 and EN 61869-3 conflict with definitions of the same terms as given in IEC 60050-811:1991 or of the other railway applications documents listed in the normative references, the definitions in

25、 EN 61869-1 and EN 61869-3 are to be used. NOTE The suffix N which appears in this standard for rated values is not present in EN 618691 and EN 618693. References in subclauses of EN 61869-1 and EN 61869-3 have to be replaced by references to applicable subclauses in this standard as far as reasonab

26、ly possible. BS EN 50152-3-3:2016EN 50152-3-3:2016 (E) 4 EN 50152 Series under the generic title “Railway applications - Fixed installations - Particular requirements for a.c. switchgear” is divided as follows: Part 1: Circuit-breakers with nominal voltage above 1 kV; Part 2: Disconnectors, earthing

27、 switches and switches with nominal voltage above 1 kV; Part 3-1: Measurement, control and protection devices for specific use in a.c. traction systems Devices; Part 3-2: Measurement, control and protection devices for specific use in a.c. traction systems Current transformers; Part 3-3: Measurement

28、, control and protection devices for specific use in a.c. traction systems Voltage transformers. BS EN 50152-3-3:2016EN 50152-3-3:2016 (E) 5 1 Scope This EN 50152-3-3 is applicable to new voltage transformers which are: intended for use in indoor or outdoor fixed installations in tractions systems,

29、and operated with an a.c. line voltage and frequency as specified in EN 50163. NOTE 1 EN 50163 specifies the a.c. traction systems 15 kV 16,7 Hz and 25 kV 50 Hz. NOTE 2 As rails of a.c. traction systems are typically connected to earth and included in the return current path, all phase to earth volt

30、ages are subject to the limits as given in EN 50163. Nevertheless conductor to conductor voltages are some times higher e.g. in autotransformer systems. Voltage transformers are mainly used with: measuring instruments, protective devices. This EN 50152-3-3 also applies to voltage transformers other

31、than inductive types as far as reasonably possible. Requirements of this EN 50152-3-3 have priority. NOTE 3 Combined current and voltage transformers also capacitive voltage transformers are typically not used in fixed installations in traction systems. 2 Normative references The following documents
