Foreword
This Technical Specification was prepared by the Technical Committee CENELEC TC 37A,
Low voltage surge protective devices.
It also concerns the expertise of SC 9XC, Electric supply and earthing systems for public transport
equipment and ancillary apparatus (Fixed installations), of Technical Committee CENELEC TC 9X,
Electrical and electronic applications for railways.
The broad subject of overvoltage protection in d.c. traction systems need to address the approaches,
requirements and definitions of several disciplines and TC’s. Concerned European Standards are
referenced for generic definitions.
This Technical Specification reflects the common practise of overvoltage protection in the d.c. traction
community, as far as protection of equipment in the primary power supply is concerned (e.g. feeders,
overhead contact lines, return circuits, power side of rolling stock).
Therefore, definitions and approaches in this Technical Specification, covering a specific application in
line with EN 50526-1, are different for some aspects from the definitions and approaches in the
EN 61643 series.
The text of the draft was circulated for voting in accordance with the Internal Regulations, Part 2,
Subclause 11.3.3.3. and was approved by CENELEC as CLC/TS 50544 on 2009-12-25.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following date is proposed:
– latest date by which the existence of the CLC/TS

has to be announced at national level
(doa) 2010-06-25

This Technical Specification will be withdrawn once the SC 9XC document on the same subject is
published.

Railway applications - Fixed installations - Electrical safety, earthing and the return circuit - Part 2: Provisions against the effects of stray currents caused by DC traction systems
SIST EN 50122-2:2022

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.

Railway applications - Fixed installations - Electrical safety, earthing and the return circuit - Part 3: Mutual Interaction of AC and DC traction systems
SIST EN 50122-3:2022

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.

Railway application - Fixed installations - D.C. surge arresters and voltage limiting devices - Part 3: Application Guide
SIST EN 50526-3:2016

This Application Guide supports the European Standards EN 50526 1 and EN 50526 2. Guidance is offered on the following subjects. – The selection and installation of surge arresters – The selection and installation of voltage limiting devices as VLD-O and VLD-F. – The arrangement of the surge arresters and VLDs Because of differences in the established, proven methods, electric traction systems of nominal voltage 600 V – 750 V are treated separately from the systems at higher nominal voltages. This application guide does not treat systems different from the d.c. electrified traction systems

SIST EN IEC 61300-2-44:2024

IEC 61300-2-44:2024 specifies a test to determine the influence of flexing under tensile load of the strain relief of fibre optic interconnecting devices or components. The intention is to simulate the number of flexing cycles which would typically be experienced during service life. This test is applied to both single fibre cable and multiple fibre cable. This fourth edition cancels and replaces the third edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) replaced active monitoring with transient loss for measurements during test; b) harmonized recommended severities according to IEC 61753-1.

Underwater acoustics - Calibration of acoustic wave vector receivers in the frequency range 5 Hz to 10 kHz
SIST EN IEC 63305:2024

IEC 63305:2024 specifies methods and procedures for calibration of vector receivers in the frequency range 5 Hz to 10 kHz, which are applicable to vector receivers based on the two different principles. In addition, it describes an absolute method of inertial vector receiver calibration in air using optical interferometry. Usually, acoustic wave vector receivers are designed and constructed based on one of two principles. One is the sound pressure difference (gradient) principle. When measuring with this sensor, the vector receiver is rigidly fixed on a mount and supported in water. The other is the co-vibrating (inertial) principle. When measuring with this sensor, the vector receiver is suspended on a mount and supported in water in a non-rigid manner, which allows the vector receiver co-vibrate in the same direction as the sound particle in the sound wave field. Many methods have been used to calibrate vector receivers, such as free-field calibration, calibration in standing wave tube and calibration in a travelling wave tube.
