21、ause minimal disturbance to other equipment. The levels, however, do not cover the following cases: a) where the probability of an occurrence likely to produce emissions in excess of those which would normally be experienced is extremely low, b) where highly susceptible apparatus will be used in clo

22、se proximity of the equipment covered by this standard, in which case further measures 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. 1 Scope This European Standard applies to emission and immu

23、nity aspects of EMC for electrical and electronic apparatus and systems intended for use in railway fixed installations associated with power supply. This includes the power feed to the apparatus, the apparatus itself with its protective control circuits, trackside items such as switching stations,

24、power autotransformers, 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 ha

25、s special requirements. 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. The limits in this standard do not apply to intentional communication signals. The frequency range

26、 considered is from d.c. to 400 GHz. No measurements need to be performed at frequencies where 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 t

27、he track for the purpose of controlling or regulating the railway power supply, including power factor correction and filtering; c) along the track for the purpose of supplying electrical power to the railway other than by means of the conductors used for contact current collection, and associated r

28、eturn conductors. Included are high voltage feeder systems within the boundary of the railway which supply substations at which the voltage is reduced to the railway system voltage. NOTE 1 Examples are one conductor of a 25-0-25 kV 50 Hz system and the 110 kV 16,7 Hz supply systems. NOTE 2 Similar c

29、onductors which are outside the railway boundary are treated as in the public area and are considered to be general overhead power lines although they feed only the railway. d) beside the track for controlling or regulating electric power supplies to ancillary railway uses. This category includes po

30、wer supplies to marshalling yards, maintenance depots and stations; e) various other non-traction power supplies from railway sources which are shared with railway traction. Apparatus and systems which are in an environment which can be described as residential, commercial or light industry, even wh

31、en placed within the physical boundary of the railway substation, shall comply with the relevant generic European EMC standard. 4 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 of this standard. N

32、OTE 3 An example is an 18 MVA 230 kV to 25 kV power supply transformer. These specific provisions are to be used in conjunction with the general provisions in EN 50121-1.
