Railway applications - Electromagnetic compatibility - Part 5: Emission and immunity of fixed power supply installations and apparatus
SIST EN 50121-5:2017/A1:2020

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.

Railway applications - Electromagnetic compatibility - Part 4: Emission and immunity of the signalling and telecommunications apparatus
SIST EN 50121-4:2017/A1:2019

This European Standard applies to signalling and telecommunication apparatus that is installed inside the railway environment. Signalling and telecommunication apparatus mounted in vehicles is covered by EN 50121-3-2:2016, signalling and telecommunication apparatus installed inside the substation and connected to substation equipment is covered by EN 50121-5:2016. This European Standard specifies limits for emission and immunity and provides performance criteria for signalling and telecommunications (S&T) apparatus (including power supply systems belonging to S&T) which may interfere with other apparatus inside the railway environment, or increase the total emissions for the railway environment and so risk causing Electro-Magnetic Interference (EMI) to apparatus outside the railway system. The requirements specified in this standard apply for: — vital equipment such as interlocking or command and control; — 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. Other apparatus not covered by at least one of these given cases should be in compliance with EN 61000-6-2. 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. Immunity limits do not apply in the exclusion bands as defined in the corresponding EMC related standard for radio equipment. The standard does not specify basic personal safety requirements for apparatus such as protection against electric shock, unsafe operation, insulation co-ordination and related dielectric tests. The requirements were developed for and are applicable to this set of apparatus when operating under normal conditions. Fault conditions of the apparatus have not been taken into account. The frequency range considered is from DC to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified. For products in the scope of EN 61000-3-2, EN 61000-3-3, EN 61000-3-11 or EN 61000-3-12 the requirements of those standards also apply. These specific provisions are to be used in conjunction with the general provisions in EN 50121-1:2016. The immunity and emission levels do not of themselves guarantee that the integration of apparatus will necessarily be satisfactory. The standard cannot cover all the possible configurations of the apparatus, but the test levels are sufficient to achieve satisfactory EMC in the majority of cases.

Railway Applications - The Specification and Demonstration of Reliability, Availability, Maintainability and Safety (RAMS) - Part 1: Generic RAMS Process
SIST EN 50126-1:2018

This part 1 of EN 50126 - considers RAMS, understood as reliability, availability, maintainability and safety and their interaction; - considers the generic aspects of the RAMS life cycle. The guidance in this part can still be used in the application of specific standards; - defines: - a process, based on the system life cycle and tasks within it, for managing RAMS; - a systematic process, tailorable to the type and size of the system under consideration, for specifying requirements for RAMS and demonstrating that these requirements are achieved; - addresses railway specifics; - enables conflicts between RAMS elements to be controlled and managed effectively; - does not define: - RAMS targets, quantities, requirements or solutions for specific railway applications; - rules or processes pertaining to the certification of railway products against the requirements of this standard; - an approval process for the railway stakeholders. This part 1 of EN 50126 is applicable to railway application fields, namely Command, Control and Signalling, Rolling Stock and Fixed Installations, and specifically: - to the specification and demonstration of RAMS for all railway applications and at all levels of such an application, as appropriate, from complete railway systems to major systems and to individual and combined subsystems and components within these major systems, including those containing software; in particular: - to new systems; - to new systems integrated into existing systems already accepted, but only to the extent and insofar as the new system with the new functionality is being integrated. It is otherwise not applicable to any unmodified aspects of the existing system; - as far as reasonably practicable, to modifications and extensions of existing systems already accepted, but only to the extent and insofar as existing systems are being modified. It is otherwise not applicable to any unmodified aspect of the existing system; - at all relevant phases of the life cycle of an application; - for use by railway duty holders and the railway suppliers. It is not required to apply this standard to existing systems which remain unmodified, including those systems already compliant with any former version of EN 50126. The process defined by this European Standard assumes that railway duty holders and railway suppliers have business-level policies addressing Quality, Performance and Safety. The approach defined in this standard is consistent with the application of quality management requirements contained within EN ISO 9001.

Railway applications - Electromagnetic compatibility - Part 2: Emission of the whole railway system to the outside world
SIST EN 50121-2:2017

This European Standard is intended to define the electromagnetic environment of the whole railway system including urban mass transit and light rail system. It describes the measurement method to verify the emissions, and gives the cartography values of the fields most frequently encountered. This European Standard specifies the emission limits of the whole railway system to the outside world. The emission parameters refer to the particular measuring points defined in Clause 5. These emissions should be assumed to exist at all points in the vertical planes which are 10 m from the centre lines of the outer electrified railway tracks, or 10 m from the fence of the substations. Also, the zones above and below the railway system may be affected by electromagnetic emissions and particular cases need to be considered individually. These specific provisions need to be used in conjunction with the general provisions in EN 50121-1. For existing railway lines, it is assumed that compliance with the emission requirements of EN 50121-3-1, EN 50121-3-2, EN 50121-4 and EN 50121 5 will ensure the compliance with the emission values given in this part. For newly build railway systems it is best practice to provide compliance to the emission limits given in this part of the standard (as defined in the EMC plan according to EN 50121-1).

Railway applications - Electromagnetic compatibility - Part 1: General
SIST EN 50121-1:2017

This European standard outlines the structure and the content of the whole set. It specifies the performance criteria applicable to the whole standards series. Clause 5 provides information about the EMC management. This part alone is not sufficient to give presumption of conformity to the essential requirements of the EMC-Directive and is intended to be used in conjunction with other parts of this standard. Annex A describes the characteristics of the railway system which affect electromagnetic compatibility (EMC) behaviour. Phenomena excluded from the set are Nuclear EM pulse, abnormal operating conditions (e.g. fault conditions) and the induction effects of direct lightning strike. Emission limits at the railway system boundary do not apply to intentional transmitters within the railway system boundaries. Safety considerations are not covered by this set of standards. The biological effects of non-ionizing radiation as well as apparatus for medical assistance, such as pacemakers, are not considered here.

Railway applications - Fixed installations - Particular requirements for alternating current switchgear - Part 1: Circuit-breakers with nominal voltage above 1 kV
SIST EN 50152-1:2013

This EN 50152-1 is applicable to single-pole and two-pole alternating current (a.c.) circuit-breakers which are: - for indoor or outdoor fixed installations in tractions systems, 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 connected to earth and included in the return current path all phase to earth voltages will be within the tolerances as specified in EN 50163. Nevertheless phase to phase voltages are sometimes higher e.g. in autotransformer systems. This European Standard is also applicable to the operating devices of circuit-breakers and to their auxiliary equipment. This European Standard does not address circuit-breakers with dependent manual operating mechanism. NOTE 3 It is impossible to specify a rated short-circuit making current for these circuit-breakers and it is likely that such dependent manual operation is not meeting safety considerations.
