Components for low-voltage surge protection - Part 352: Selection and application principles for telecommunications and signalling network surge isolation transformers (SITs)
SIST EN IEC 61643-352:2018

IEC 61643-352:2018 covers the application of surge isolation transformers (SITs) that are used in telecommunication transformer applications with signal levels up to 400 V peak to peak. These transformers have a high rated impulse voltage with or without screen between the input and output windings. SITs are components for surge protection and are used to mitigate the onward propagation of common-mode voltage surges. This document describes SITs' selection, application principles and related information. This document does not cover power line communication transformers.

Railway applications - Environmental conditions for equipment -- Part 3: Equipment for signalling and telecommunications
EN 50125-3:2003

This European Standard specifies the environmental conditions encountered within Europe. It can also be applied elsewhere by agreement between the supplier and the customer.
The scope of this European Standard covers the design and the use of equipment and any portable equipment for signalling and telecommunications systems (including test, measure, monitoring equipment, etc.).
The portable equipment must comply with the sections of this European Standard relevant to their use.
This European Standard does not specify the test requirements for equipment.
In particular the standard intends to define
–   interface conditions between the equipment and its environment,
–   parameters to be used by designers when calculating R.A.M.S. and life time with respect to environmental condition effects.
In this respect it gives general guidance in order to allow consistent assessments of contract documentation for European projects.
The defined environmental conditions are considered as normal in service.
Microclimates surrounding components may need special requirements to be defined by the product standard.
The effects of any signalling and telecommunications equipment (in either or failure mode of operation) on the overall signalling system safety are not within the scope of this European Standard. This European Standard does not provide the designer with information to enable him to determine the safety risk associated with environmental conditions. The safety of persons in the vicinity of (or working on) the signalling and telecommunications equipment is also out of the scope of this European Standard. The effects of vandalism on the equipment are not considered in this European Standard.
This European Standard applies to all signalling and telecommunications systems except those used for cranes, mining vehicles and cable cars. It does not define the specifications for train-borne signalling and telecommunications systems.
The train-borne signalling and telecommunications systems must comply with rolling stock environmental conditions specifications (EN 50125-1).

Lightning protection - Telecommunication lines - Part 2: Lines using metallic conductors

Deals with protection against lightning of outdoor telecommunication lines using metallic conductors (for example, access networks, lines between buildings). These lines concern: - telecommunication lines connecting a switch with a network termination (NT1) - telecommunication or signal lines connecting equipment located in different buildings, e.g. ISDN lines or signal lines between computers. The object of this standard is to protect telecommunication lines and connected equipment against the direct and indirect influence of lightning by limiting the risk of damage due to overvoltages and overcurrents, liable to occur in these lines, to values which are lower than or equal to tolerable risk of damage. The type of building can also have an effect on the risk assessment of lightning damage to telecommunication lines, as well as the physical layout of the equipment installation. However, these and other similar aspects are covered by appropriate, specific standards and are beyond the scope of this standard. Fibre optical cable with metallic pairs in the cable core must be protected, following the requirements of this standard, together with those requirements defined in IEC 61663-1.

Objective is to limit the number of possible primary failures occurring in the optical fibre cable in a specified installation to within values which are lower than or equal to the limit value, defined as the tolerable frequency of primary failures. Gives the method for calculating the possible number of primary failures, choosing the feasible protective measures and indicating the tolerable frequency of primary failures. Secondary failures are not considered. The tests described in annex G are convenient only for the risk evaluation associated with lightning in fibre optic installations.
