| Resumen: | This European Standard applies to emission and immunity aspects 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 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 has 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 considered is from DC 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:
The immunity levels given in this standard apply for
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, shall comply with the relevant generic European EMC standard. 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. NOTE 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 . This part of the standard covers requirements for both apparatus and fixed installations. The sections for fixed installations are not relevant for CE marking. |
