EN 50121-5:2017 includes the following significant technical changes with respect to EN
18、 50121-5:2015: - clarification of scope (Clause 1); - set dated normative references (Clause 2); - emission requirement extended in the frequency range 1 GHz to 6 GHz following EN 61000-6-4; - immunity requirement extended in the frequency range 5,1 GHz to 6 GHz; - removal of limits for radiated H-f
19、ields in the frequency range 9 kHz to 150 kHz due to the fact that: - there are very few outside world victims; - there is low reproducibility; - revision of Annex ZZ. This European Standard is to be read in conjunction with EN 50121-1. Attention is drawn to the possibility that some of the elements
20、 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 document has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association, and supports essential requ
21、irements of EU Directive(s). For the relationship with EU Directive(s) see informative Annex ZZ, which is an integral part of this document. This standard forms Part 5 of the European Standard series EN 50121, published under the general title “Railway applications - Electromagnetic compatibility”.

24、e to other equipment. The levels, however, do not cover the following cases: a) which may occur with an extremely low probability of occurrence in any location;b) where highly susceptible apparatus will be used in close proximity of the equipment covered bythis standard, in which case further measur
25、es may have to be taken.The emission limits given are on the basis that the equipment of the product family range is installed in railway substation areas. BS EN 50121-5:2017EN 50121-5:2017 (E)4BS EN 50121-5:2017EN 50121-5:2017 (E) 5 1 Scope This European Standard applies to emission and immunity as
26、pects of EMC for electrical and electronic apparatus and systems intended for use in railway fixed installations for power supply. This includes the power feed to the apparatus, the apparatus itself with its protective control circuits, trackside items such as switching stations, power autotransform
27、ers, booster transformers, substation power switchgear and power switchgear to other longitudinal and local supplies. Filters operating at railway system voltage (for example, for harmonic suppression or power factor correction) are not included in this standard since each site has special requireme
28、nts. Filters would normally have separate enclosures with separate rules for access. If electromagnetic limits are required, these will appear in the specification for the equipment. If a port is intended to transmit or receive for the purpose of radio communication (intentional radiators, e.g. tran
29、sponder systems), then the radiated emission requirement in this standard are not intended to be applicable to the intentional transmission from a radio-transmitter as defined by the ITU. The frequency range considered is from DC to 400 GHz. No measurements need to be performed at frequencies where
30、no requirement is specified. Emission and immunity limits are given for items of apparatus which are situated: a) within the boundary of a substation which delivers electric power to a railway;b) beside the track for the purpose of controlling or regulating the railway power supply, includingpower f
31、actor correction;c) along the track for the purpose of supplying electrical power to the railway other than by means ofthe conductors used for contact current collection, and associated return conductors. Included arehigh voltage feeder systems within the boundary of the railway which supply substat
32、ions at whichthe voltage is reduced to the railway system voltage;d) beside the track for controlling or regulating electric power supplies to ancillary railway uses. Thiscategory includes power supplies to marshalling yards, maintenance depots and stations;e) various other non-traction power suppli
33、es from railway sources which are shared with railwaytraction.The immunity levels given in this standard apply for: - vital equipment such as protection devices; - equipment having connections to the traction power conductors; - apparatus inside the 3 m zone; - ports of apparatus inside the 10 m zon
34、e with connection inside the 3 m zone; - ports of apparatus inside the 10 m zone with cable length 30 m. Apparatus and systems which are in an environment which can be described as residential, commercial or light industry, even when placed within the physical boundary of the railway substation, sha
35、ll comply with EN 61000-6-1:2007 for immunity and EN 61000-6-3:2007 for emission requirements. Excluded from the immunity requirements of this standard is power supply apparatus which is intrinsically immune to the tests defined in Tables 1 to 6. NOTE An example is an 18 MVA 230 kV to 25 kV power su
36、pply transformer. These specific provisions are to be used in conjunction with the general provisions in EN 50121-1.

49、50121-1. 5 Emission tests and limits 5.1 Emission from the substation to the outside world Limit values for this emission, over the frequency range 150 kHz to 1 GHz are given in EN 50121-2. Guidance values are given in EN 50121-2 for emission of DC and power frequency magnetic fields. Conductors (overhead or underground) between the substation and the railway are part of the railway installation, but because of their wide variety of positions and ampere loadings, limit values cannot be set for the magnetic fields which they produce.
