Scope: 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. If a port is intended to transmit or receive for the purpose of radio communication (intentional radiators, e.g. transponder 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 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, including power factor correction; 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 return 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; d) beside the track for controlling or regulating electric power supplies to ancillary railway uses. This category includes power supplies to marshalling yards, maintenance depots and stations; e) various other non-traction power supplies from railway sources which are shared with railway traction. 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 zone 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, shall 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 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.Cross References:EN 61000-4-6:2009EN 50121-1:2017IEC 61000-4-5:2005IEC 61000-4-18:2006EN 50121-2:2017EN 61000-4-2:2009EN 61000-4-4:2012IEC 61000-4-3:2006EN 61000-4-3:2006IEC 61000-4-8:2009IEC 61000-4-2:2008EN 61000-4-5:2006IEC 61000-4-4:2012EN 61000-6-4:2007IEC 61000-6-4:2006IEC 61000-4-6:2008EN 61000-4-18:2007EN 61000-4-8:2010IEC 61000 3 2:2014EN 61000-3-12:2011EN 61000-3-11:2000IEC 61000-6-2:2005EN 61000-3-2:2014CISPR 16-1-1:2010EN 61000-6-2:2005EN 61000-3-3:2013IEC 61000 3 12:2011EN 55016-1-1:2010EN 50124-1:2001IEC 61000-3-11:20002014/30/EUIEC 61000-3-3:2013Incorporates the following:Amendment, May 2019
