CLC/TC 9X - Electrical and electronic applications for railways

Scope remains the same as EN50126-2:2017

This document specifies the technical parameters of track circuits associated with the interference current emissions limits for RST in the context of interoperability defined in the form of Frequency Management in ERA/ERTMS/033281 v4.0. The limits for compatibility between rolling stock and track circuits addressed in this document allow provision for known interference phenomena linked to traction power supply including associated protection (over voltage, short-circuit current and basic transient effects like in-rush current and power cut-off), and other known sources of interference. This document is intended to be used to assess compliance of track circuits and other forms of train detection systems using the rails as part of their detection principles, in the context of the European Directive on the interoperability of the trans-European railway system and the associated technical specification for interoperability relating to the control-command and signalling track-side subsystems. The document describes technical parameters to consider for achieving the compatibility of the track circuit with the emissions limits defined in the frequency management for rolling stock (ERA/ERTMS/033281 v4.0). These parameters are structured and allocated according to their basic references as follows: - technical track circuit parameters; - train based parameters; - track based parameters; - environmental and other parameters including EMC. Each parameter is defined by a short general description, the definition of the requirement, the relation to other standards and a procedure to show the fulfilment of the requirement as far as necessary. An overview of the safety relevance of each parameter is given - in the context of this document - in a separate table. This document is applicable to track circuits on all lines, including non-electrified lines. However, for track circuits intended to be installed only on non-electrified lines, some parameters can be disapplied.

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.

The shore supply system is used while the rolling stock is standing still within depots and sidings location for providing power to the AC auxiliary loads (which can include battery charging) when the primary power supply (contact line) is not available or used. This document: - specifies requirements to the shore supply and to the rolling stock for safe operation on shore supply operation; - specifies the requirements to ensure compatibility of class C0 and C1 train types as given in CLC/TS 50534:2010 systems and three-phase shore power supply systems; - provides a complete system design for 63/125 A shore supplies including the interfaces (power and control loop) between shore supply and rolling stock; - specifies the requirements with regards to interoperability with AC and DC fed traction systems in order to prevent undesired stray currents and adverse interaction with signalling systems when operating on shore supply; - defines the electrical characteristics of the 63/125 A shore power supply; - defines the 63/125 A connectors and its intermateability to provide interoperability for rolling stock that is to run across borders; - defines the 600 A connector and its intermateability; - can be used for other type of rail vehicles and purposes, if agreed by the manufacturer and customer - does not apply to shore supplies to move the rolling stock; - does not describe the 600 A shore supply system. NOTE 1 The 600 A connector is the existing UK standard three-phase shore supply connector which has a long service history. NOTE 2 The connectors are dimensioned using standard rolling stock cables as set out in EN 50264-3-1:2008. NOTE 3 Examples of other usage and rail vehicles are: e.g. light rail vehicles, class A train types, traction battery charging etcetera.

This document specifies requirements for the installation of cabling on railway vehicles and within electrical enclosures on railway vehicles, including magnetic levitation trains and trolley buses. NOTE With respect to trolley buses, this document applies to the whole electric traction system, including current collecting circuits, power converters and the respective control circuits. The installation of other circuits is covered by street vehicle standards for example those for combustion driven buses. This document covers cabling for making electrical connections between items of electrical equipment, including cables, busbars, terminals and plug/socket devices. It does not cover special effect conductors like fibre optic cables or hollow conductors (waveguides). The material selection criteria given here are applicable to cables with copper conductors. This document is not applicable to the following: - special purpose vehicles, such as track-laying machines, ballast cleaners and personnel carriers; - vehicles used for entertainment on fairgrounds; - vehicles used in mining; - electric cars; - funicular railways. As the field of cabling in rolling stock is also dealt with in the cable makers’ standard, references are made to EN 50264 series, EN 50306 series, EN 50382 series and EN 50355. This document applies in conjunction with the relevant product and installation standards and describes minimum requirements.

This document specifies parameters for the design and usage of axle counter systems. For this, this document specifies the technical parameters of axle counter systems associated with the magnetic field limits for RST in the context of interoperability. In addition, test methods are defined for establishing the conformity and the performance of an axle counter detector. This document is intended to be used to assess compliance of axle counter systems and other forms of wheel sensors used for train detection, in the context of the European Directive on the interoperability of the trans-European railway system and the associated technical specification for interoperability relating to the control-command and signalling track-side subsystems. This document can also be used for axle counter systems installed on lines which are not declared as interoperable (including metro and tram lines). For wheel sensors and wheel detectors in other applications than axle counters but using the same sensors on the rail and detection circuits, transient and continuous interference can be considered as equivalent to axle counter detectors or axle counter sensors. Under interoperability, the frequency bands and rolling stock emission limits are currently defined in the axle counter FrM as specified in the ERA/ERTMS/033281 document.

1.1 This document specifies the process and technical requirements for the development of software for programmable electronic systems for use in: - control, command for signalling applications, - applications on-board of rolling stock. This document is not intended to be applied in the area of electric traction power supply (fixed installations) or for power supply and control of conventional applications, e.g. station power supply for offices, shops. These applications are typically covered by standards for energy distribution and/or non-railway sectors and/or local legal frameworks. 1.2 This document is applicable exclusively to software and the interaction between software and the system of which it is part. 1.3 Intentionally left blank 1.4 This document applies to software as per subclause 1.1 of this document used in railway systems, including: - application programming, - operating systems, - support tools, - firmware. Application programming comprises high level programming, low level programming and special purpose programming (for example: programmable logic controller ladder logic). 1.5 This document also addresses the use of pre-existing software (as defined in 3.1.16) and tools. Such software can be used if the specific requirements in 7.3.4.7 and 6.5.4.16 on pre-existing software and for tools in 6.7 are fulfilled. 1.6 Intentionally left blank 1.7 This document considers that modern application design often makes use of software that is suitable as a basis for various applications. Such software is then configured by application data for producing the executable software for the application. 1.8 Intentionally left blank 1.9 This document is not intended to be retrospective. It therefore applies primarily to new developments and only applies in its entirety to existing systems if these are subjected to major modifications. For minor changes, only 9.2 applies. However, application of this document during upgrades and maintenance of existing software is advisable. 1.10 For the development of User Programmable Integrated Circuits (e.g. field programmable gate arrays (FPGA) and complex programmable logic devices (CPLD)) guidance is provided in EN 50129:2018 Annex F for safety related functions and in EN 50155:2017 for non-safety related functions. Software running on softcore processors of User Programmable Integrated Circuits is within the scope of this document.

Add the following note after the paragraph in 1.6: 'NOTE This document was derived from the signalling standard EN 50128 which in many cases was also applied in Rolling Stock applications. Subclause 1.6 ensures continuity in the application of the standards, i.e., software that was developed in accordance with EN 50128 can still be re-used for new projects.'

This document provides railway operators, system integrators and product suppliers, with guidance and specifications on how cybersecurity will be managed in the context of EN 50126 1 RAMS lifecycle process. This document aims at the implementation of a consistent approach to the management of the security of the railway systems. This document can also be applied to the security assurance of systems and components/equipment developed independently of EN 50126 1:2017. This document applies to Communications, Signalling and Processing domain, to Rolling Stock and to Fixed Installations domains. It provides references to models and concepts from which requirements and recommendations can be derived and that are suitable to ensure that the residual risk from security threats is identified, supervised and managed to an acceptable level by the railway system duty holder. It presents the underlying security assumptions in a structured manner. This document does not address functional safety requirements for railway systems but rather additional requirements arising from threats and related security vulnerabilities and for which specific measures and activities need to be taken and managed throughout the lifecycle. The aim of this document is to ensure that the RAMS characteristics of railway systems / subsystems / equipment cannot be reduced, lost or compromised in the case of cyber attacks. The security models, the concepts and the risk assessment process described in this document are based on or derived from the IEC/EN IEC 62443 series. This document is consistent with the application of security management requirements contained within IEC 62443 2 1, which in turn are based on EN ISO/IEC 27001 and EN ISO 27002.

This International Standard retains IEC 61984:2008 as the minimum performance requirements for railway rolling stock electrical connectors. It identifies additional terms, test methods and performance requirements for single-pole and multipole connectors with rated voltages up to 1 000 V, rated currents up to 125 A per contact and frequencies below 3 MHz used for indoor and outdoor applications in railway rolling stock. This International Standard does not cover: - connectors with breaking capacity (CBCs) as defined in IEC 61984:2008, 3.2, because on board rolling stock connectors are not intended to be operated (i.e. mated and unmated) under load or when live, either by means of procedures or by the presence of interlocks, as required by IEC 61991; - non-rewirable connectors as defined in IEC 61984:2008, 3.5; - automatic couplers, due to their additional mechanical complexity and the need for more specific requirements and testing; - inter-vehicle jumpers, as they are connector and cable assemblies whose characteristics depend on those of both elements. Inter-vehicle connectors within the limits set in the scope of this International Standard are therefore covered by the agreed choice of suitable mechanical and environmental characteristics as defined by Annex B, and suggested by Annex C. This International Standard identifies the application levels for electrical connectors based on a) the severity of the service conditions in different rolling stock technologies, b) the intended use of the rolling stock, c) the location of the connector in the rolling stock system. This International Standard is not applicable to internal connections of electronic devices such as connectors for printed boards and rack-and-panel connectors.

This document specifies requirements for the acceptance of simulation tools used for the assessment of design of electric traction power supply systems with respect to TSI Energy. This document is applicable to the simulation of AC and DC electric traction power supply systems, in the frame of assessment required by Directive (EU) 2016/797. The methods and parameters defined in this document are only intended for use in the design of the electric traction power supply system, and hence this document solely considers validation of tools within the TSI energy subsystem for all envisaged railway networks. This document does not deal with validation of simulation tools by measurement. This document focuses on the core simulation functions comprising the equations and functions which calculate the mechanical movement of trains and also which calculate the load flow of the electrical traction power supply system. In doing so this document provides all requirements necessary to demonstrate that a simulation tool may be used for the purposes of TSI approval of electric traction power supply systems. Any simulation tool which meets the acceptance requirements of the test cases in this document can be used to determine TSI compatibility for all systems of the same voltage and frequency without any requirement for further validation as part of the TSI assessment process. This document includes controls for the modification of simulation tools, in particular the limits of applicability of certification when tools are modified. These controls focus on determining whether the core functions of the simulation model are modified. This document provides only the requirements for demonstration of the algorithms and calculations of core functions. The use of a certified simulation tool in accordance with this document does not, in itself, demonstrate good practice in electric traction power supply system design, neither does it guarantee that the simulation models and data for infrastructure or trains used in the tool are correct for a given application. The choice and application of any models and data, of individual system components, in a design is therefore subject to additional verification processes and not in the Scope of this document. Competent development of design models and full understanding of the limits of design tools remain requirements in any system design. This document does not reduce any element of the need for competent designers to lead the design process. The test cases and data shown in Clause 6 in this document do not represent an existing network, but these data are used as theoretical/virtual network only for the purpose of verification of the core functionality. NOTE A new test case will be drafted considering metro, tramways and trolleybuses using DC 600 V or DC 750 V. Until this test case is available, this document can also be applied to subway, tram and trolley bus systems. This test case will also integrate rail systems using DC 750 V. Additionally, the application of this document ensures that the output data of different simulation tools are consistent when they are using the same set of input data listed in Clause 6. This document only applies to the simulation of electric traction power supply systems characteristics at their nominal frequency for AC or DC systems. It does not consider harmonic studies, electrical safety studies (e.g. rail potential), short circuit or electromagnetic compatibility studies over a wide frequency spectrum. This document does not mandate the use of a particular simulation tool in order to validate the design of an electric traction power supply system. This document does not consider complex models with active components such as static frequency convertors.

IEC 62290-3:2019 specifies the system architecture for Urban Guided Transport Management and Command/Control systems (UGTMS) as defined in IEC 62290-1 and IEC 62290-2, and the allocation of functions and requirements defined in IEC 62290-2 to the different UGTMS subsystems (designated as system constituents in IEC 62290-1 and IEC 62290-2), for use in urban guided passenger transport lines and networks. This document is applicable for new lines or for upgrading existing signalling and command control systems. This document is applicable to applications using: - continuous data transmission - continuous supervision of train movements by train protection profile - localisation by reporting trains, and optionally by external wayside equipment for non-reporting ones (e.g. in case of mixed operation or degraded operation) This document is applicable as a basis to define FIS and FFFIS. For specific applications, some elements may be added to meet the requirements coming from additional functions or equipment.

This document specifies requirements for the technical compatibility between pantographs and overhead contact lines, to achieve free access to the lines of the European railway network. NOTE These requirements are defined for a limited number of pantograph types conforming to the requirements in 5.3, together with the geometry and characteristics of compatible overhead contact lines.

This document describes a process to demonstrate compatibility between Rolling Stock (RST) and Train Detection Systems (TDS). It describes the characterization of train detection systems, rolling stock and traction power supply systems. It is worth noting that the demonstration of technical compatibility between the rolling stock and infrastructure with respect to physical dimensions is not detailed in this document. This document is not generally applicable to those combinations of rolling stock, traction power supply and train detection system which were accepted as compatible prior to the issue of this document. However, as far as is reasonably practicable, this document can be applied to modifications of rolling stock, traction power supply or train detection systems which may affect compatibility. The detailed process can be used where no rules and processes for compatibility are established.

This document specifies requirements for protective provisions against the effects of stray currents, which result from the operation of DC electric traction power supply systems. As several decades' experience has not shown evident corrosion effects from AC electric traction power supply systems, this document only deals with stray currents flowing from a DC electric traction power supply system. This document applies to all metallic fixed installations which form part of the traction system, and also to any other metallic components located in any position in the earth, which can carry stray currents resulting from the operation of the railway system. This document applies to all new DC lines and to all major revisions to existing DC lines. The principles can also be applied to existing electrified transportation systems where it is necessary to consider the effects of stray currents. This document does not specify working rules for maintenance but provides design requirements to allow maintenance. The range of application includes: a) railways, b) guided mass transport systems such as: 1) tramways, 2) elevated and underground railways, 3) mountain railways, 4) magnetically levitated systems, which use a contact line system, and 5) trolleybus systems, c) material transportation systems. This document does not apply to a) electric traction power supply systems in underground mines, b) cranes, transportable platforms and similar transportation equipment on rails, temporary structures (e.g. exhibition structures) in so far as these are not supplied directly from the contact line system and are not endangered by the electric traction power supply system, c) suspended cable cars, d) funicular railways.

This document specifies requirements for the protective provisions relating to electrical safety in fixed installations, when it is reasonably likely that hazardous voltages or currents will arise for people or equipment, as a result of the mutual interaction of AC and DC electric power supply traction systems. It also applies to all aspects of fixed installations that are necessary to ensure electrical safety during maintenance work within electric power supply traction systems. The mutual interaction can be of any of the following kinds: — parallel running of AC and DC electric traction power supply systems; — crossing of AC and DC electric traction power supply systems; — shared use of tracks, buildings or other structures; — system separation sections between AC and DC electric traction power supply systems. The scope is limited to galvanic, inductive and capacitive coupling of the fundamental frequency voltages and currents and their superposition. This document applies to all new lines, extensions and to all major revisions to existing lines for the following electric traction power supply systems: a) railways; b) guided mass transport systems such as: 1) tramways, 2) elevated and underground railways, 3) mountain railways, 4) magnetically levitated systems, which use a contact line system, 5) trolleybus systems, and 6) electric traction power supply systems for road vehicles, which use an overhead contact line system; c) material transportation systems. The document does not apply to: a) electric traction power supply systems in underground mines; b) cranes, transportable platforms and similar transportation equipment on rails, temporary structures (e.g. exhibition structures) in so far as these are not supplied directly or via transformers from the contact line system and are not endangered by the electric traction power supply system for railways; c) suspended cable cars; d) funicular railways; e) procedures or rules for maintenance. The rules given in this document can also be applied to mutual interaction with non-electrified tracks, if hazardous voltages or currents can arise from AC or DC electric traction power supply systems.

This European Standard deals with long term overvoltages as shown in the Annex A.

The purpose of this document is to support rolling stock procurement, especially life cycle cost (LCC) assessment. This document is applicable to the specification and verification of energy consumption of railway rolling stock. It establishes a criterion for the energy consumption of rolling stock to calculate the total net energy consumed, either at current collector or from the fuel tank, over a predefined service profile, to ensure that the results are directly comparable or representative of the real operation of the train. For this purpose, this document considers the energy consumed and regenerated by the rolling stock. The determination methods covered are the simulation and the measurement. This document provides the framework that gives guidance on the generation of comparable energy performance values for trains and locomotives on a common basis and thereby supports benchmarking and improvement of the energy efficiency of rail vehicles. This document does not cover the comparison of energy consumption with other modes of transportation, or even for comparison between diesel and electric traction, covering only the energy consumption of the railway rolling stock itself.

This document establishes requirements for the electrical aspects to achieve technical compatibility between rolling stock and electric traction systems, limited to: - co-ordination of protection principles between power supply and traction units, i.e. separation sections, train set current or power limitation, short circuit current discrimination, breaker coordination and use of regenerative braking. - co-ordination of installed power on the line and the power demand of trains, i.e. traction unit power factor, train set current or power limitation, electric system performance, type and characterization. - compatibility assessment relating to harmonics and dynamic effects. Informative values are given for some parts of the existing European railway networks, in annexes. NOTE For those railways within the scope of EU Interoperability Directive, definitive values are set out in the register of infrastructure published in accordance with Article 49 of Directive (EU) 2016/797, and the list of items included in the register is described in the commission decision (EU) 2019/777. The following electric traction systems are within the scope of this document: - railways; - guided mass transport systems that are integrated with railways; - material transport systems that are integrated with railways. Information is given on electrification parameters to enable train operating companies to confirm, after consultation with the rolling stock manufacturers, that risks of non-compatibility are minimized and that there will be no consequential disturbance on the electrification system. The interaction between pantograph and overhead contact line is dealt with in EN 50367:2020. The interaction with the control-command and signalling subsystem is not dealt with in this document. Basic considerations have been included concerning the use of accumulator trains.

This European Standard specifies the functional requirements for output and accuracy of measurements of the dynamic interaction between pantograph and overhead contact line.

This document specifies minimum functional requirements for urban rail signalling and control systems - which operate on line of sight or using automatic interlock signalling with intermittent train control, - not covered by the existing UGTMS standard EN 62290 series, - not forming a part of an urban traffic control system but possibly interfaced with such systems. The document is restricted to minimum functional requirements which allow users to define more specific requirements based on the given framework of the system requirements at top level. This document is not applicable to command and control systems for urban rail using continuous data transmission and continuous supervision of train movements by train protection profile (already covered by the EN 62290 series).

Simulation techniques are used to assess the dynamic interaction between overhead contact lines and pantographs, as part of the prediction of current collection quality. This document specifies functional requirements for the validation of such simulation methods to ensure confidence in, and mutual acceptance of the results of the simulations. This document deals with: - input and output parameters of the simulation; - comparison with line test measurements, and the characteristics of those line tests; - validation of pantograph models; - comparison between different simulation methods; - limits of application of validated methods to assessments of pantographs and overhead contact lines. This document applies to the current collection from an overhead contact line by pantographs mounted on railway vehicles. It does not apply to trolley bus systems.

For the purpose of demonstrating compatibility between rolling stock and axle counter detectors, this document defines the interference limits and evaluation methods to verify rolling stock emissions. Wheel sensors and crossing loops are not covered by this document. This document gives recommended individual limits to be applied to establish compatibility between RST and all selected types of axle counter detectors, including any covered by national standards. The list of selected types of axle counters and their limits for compatibility are drawn on the basis of established performance criteria. It is expected that the trend for newly signalled interoperable lines will be fitted with types that meet the compatibility limits published in the TSI CCS Interfaces Document (ERA/ERTMS/033281). To ensure adequate operational availability, it is essential that the rolling stock complies with the defined limits; otherwise, the established availability of the valid output function of axle counter detectors may be compromised. NOTE The influences from metal parts or inductively coupled resonant circuits on the vehicle, eddy current brakes or magnetic brakes, are not covered by this document but are considered on the basis of national technical specifications. For wheel sensors and wheel detectors in other applications than axle counters but utilizing the same rail sensors and detectors, transient and continuous interference can be considered as equivalent to axle counter detectors or axle counter sensors.

IEC 61375-2-8:2021 applies to all equipment and devices implemented according to IEC 61375-2-3:2015, IEC 61375-2-5:2014 and IEC 61375-3-4:2014, i.e. it covers the procedures to be applied to such equipment and devices when the conformance should be proven. The applicability of this document to a TCN implementation allows for individual conformance checking of the implementation itself, and is a pre-requisite for further interoperability checking between different TCN implementations.

This document is applicable to safety-related electronic systems (including subsystems and equipment) for railway signalling applications. This document applies to generic systems (i.e. generic products or systems defining a class of applications), as well as to systems for specific applications. The scope of this document, and its relationship with other CENELEC standards, are shown in Figure 1. This document is applicable only to the functional safety of systems. It is not intended to deal with other aspects of safety such as the occupational health and safety of personnel. While functional safety of systems clearly can have an impact on the safety of personnel, there are other aspects of system design which can also affect occupational health and safety and which are not covered by this document. This document applies to all the phases of the life cycle of a safety-related electronic system, focusing in particular on phases from 5 (architecture and apportionment of system requirements) to 10 (system acceptance) as defined in EN 50126-1:2017. Requirements for systems which are not related to safety are outside the scope of this document. This document is not applicable to existing systems, subsystems or equipment which had already been accepted prior to the creation of this document. However, so far as reasonably practicable, it should be applied to modifications and extensions to existing systems, subsystems and equipment. This document is primarily applicable to systems, subsystems or equipment which have been specifically designed and manufactured for railway signalling applications. It should also be applied, so far as reasonably practicable, to general-purpose or industrial equipment (e.g. power supplies, display screens or other commercial off the shelf items), which is procured for use as part of a safety-related electronic system. As a minimum, evidence should be provided in such cases (more information is given in 6.2) to demonstrate either - that the equipment is not relied on for safety, or - that the equipment can be relied on for those functions which relate to safety. This document is aimed at railway duty holders, railway suppliers, and assessors as well as at safety authorities, although it does not define an approval process to be applied by the safety authorities.

IEC 61375-2-6:2018 establishes the specification for the communication between the on-board subsystems and the ground subsystems. The communication system, interfaces and protocols are specified as a mobile communication function, using any available wireless technology. This document provides requirements in order to: a) select the wireless network on the basis of QoS parameters requested by the application; b) allow TCMS and/or OMTS applications, installed on-board and communicating on the on-board communication network, to have a remote access to applications running on ground installations; c) allow applications running on ground installations to have a remote access to the TCMS and/or OMTS applications installed on-board.

This document specifies requirements for the shore supply system for auxiliaries and pre-conditioning and the related intermateable connector pairs. This standard specifies the characteristics of the connectors in order to achieve interoperability at the rolling-stock/shore power supply interface. This document does not apply to shore supplies to move the rolling stock.

This document specifies requirements for prefabricated metal-enclosed traction switchgear for alternating current with traction voltages and frequencies as specified in EN 50163:2004 and used in indoor and outdoor installations. Enclosures may include fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation. NOTE 1 EN 50163 specifies the AC traction systems 15 kV 16,7 Hz and 25 kV 50 Hz. NOTE 2 This document applies to single-phase or two-phase systems. For metal-enclosed traction switchgear containing gas-filled compartments, the design pressure is limited to a maximum of 300 kPa (relative pressure). NOTE 3 EN 62271 203 can be used as a guide for design and testing in case the design pressure of gas-filled compartments exceeds 300 kPa (relative pressure). Components contained in metal-enclosed traction switchgear are to be designed and tested in accordance with their various relevant standards. This document supplements the standards for the individual components regarding their installation in traction switchgear assemblies. This document does not preclude that other equipment may be included in the same enclosure. In such a case, any possible influence of that equipment on the traction switchgear is to be taken into account. NOTE 4 Traction switchgear having an insulation enclosure is covered by EN 62271 201. For definition see there or IEV 441 12 06.
