High-voltage switchgear and controlgear - Part 105: Alternating current switch-fuse combinations for rated voltages above 1 kV up to and including 52 kV (IEC 62271-105:2021)
EN IEC 62271-105:2023

IEC 62271-105:2021 is available as IEC 62271-105:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 62271-105:2021 applies to three-pole units for public and industrial distribution systems which are functional assemblies of switches composed of switches or switch-disconnectors and current-limiting fuses designed so as to be capable of
- breaking, at the rated voltage, any current up to and including the rated short-circuit breaking current;
- making, at the rated voltage, circuits to which the rated short-circuit breaking current applies.
This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- the document has been updated to be in alignment with the second edition of IEC 62271-1:2017;
- rated TRV has been removed (TRV is only a test parameter), as in the latest revision of IEC 62271-100;
- differentiation has been introduced between requirements expressed for fulfilling the function expected from a switch-fuse combination, from requirements only relevant when the function is performed by a stand-alone device. The goal is to avoid duplication or conflicts of requirements with a standard dealing with assemblies, when the function is implemented within such an assembly.

High-voltage switchgear and controlgear - Part 110: Inductive load switching (IEC 62271-110:2023)
EN IEC 62271-110:2023

This part of IEC 62271 is applicable to AC switching devices designed for indoor or outdoor
installation, for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above
1 000 V and applied for inductive current switching. It is applicable to switching devices
(including circuit-breakers in accordance with IEC 62271-100) that are used to switch
high-voltage motor currents and shunt reactor currents and also to high-voltage contactors used
to switch high-voltage motor currents as covered by IEC 62271-106.
Switching unloaded transformers, i.e. breaking transformer magnetizing current, is not
considered in this document. The reasons for this are as follows:
a) Owing to the non-linearity of the transformer core, it is not possible to correctly model the
switching of transformer magnetizing current using linear components in a test laboratory.
Tests conducted using an available transformer, such as a test transformer, will only be
valid for the transformer tested and cannot be representative for other transformers.
b) As detailed in IEC TR 62271-306, the characteristics of this duty are usually less severe
than any other inductive current switching duty. Such a duty can produce severe
overvoltages within the transformer winding(s) depending on the re-ignition behaviour of the
switching device and transformer winding resonance frequencies.
NOTE 1 The switching of tertiary reactors from the high-voltage side of the transformer is not covered by this
document.
NOTE 2 The switching of shunt reactors earthed through neutral reactors is not covered by this document. However,
the application of test results according to this document, on the switching of neutral reactor earthed reactors (4-leg
reactor scheme), is discussed in IEC TR 62271-306.

High-Voltage switchgear and controlgear - Insulating pressurised partitions for gas filled metal enclosures
EN 50089:2022

This document applies to pressurized partitions used in indoor and outdoor installations of high-voltage AC and DC switchgear and controlgear with rated voltages (Ur) above 1 kV AC / 1,5 kV DC and with design pressure higher than 300 kPa, where the gas is used principally for its dielectric and/or arc-quenching properties.
Gases with insulating properties are dry air, inert gases, for example sulphur hexafluoride or nitrogen or a mixture of such gases.
The partitions comprise pressurized barriers in electrical equipment not necessarily limited to the following examples:
—   circuit-breakers;
—   switch-disconnectors;
—   disconnectors;
—   earthing switches;
—   current transformers;
—   voltage transformers;
—   surge arrestors;
—   busbars and connections;
—   cable connections / terminations
—   cable bushings
—   etc.
Partitions which are only pressurized from one side are also covered.
1 kV AC / 1,5 kV DC means it is valid for the apparatus applied and where the partitions are installed, however, the application of voltages below 1 kV AC / 1,5 kV DC as in e.g. current and voltage transformer are not excluded.
This document does not apply to high voltage bushings (see EN 60137, EN 61462 and EN 62155).

High-voltage switchgear and controlgear - Part 4: Handling procedures for gases for insulation and/or switching (IEC 62271-4:2022)
EN IEC 62271-4:2022

This part of IEC 62271 applies to the procedures for handling of gases and gas mixtures for insulation and/or switching during installation, commissioning, repair, overhaul, normal and abnormal operations and disposal at the end-of-life of high-voltage switchgear and controlgear.
These procedures are regarded as minimum requirements to ensure the reliability of electric power equipment, the safety of personal working with these gases and gas mixtures and to minimize the impact on the environment. Additional requirements could be given or specified in the operating instruction manual of the manufacturer.
For each gas or gas mixture, which is known to be used in electric power equipment at the date of the publication of this document, a separate annex describes specifications, handling procedures, safety measures, etc. For gases or gas mixtures not covered by these annexes the electric power equipment manufacturer should provide the information needed, following the structure of these annexes. Such gases or gas mixtures should also be described in a next edition or in amendments to this edition.
NOTE 1 For the use of this document, high-voltage (HV) is defined as the rated voltage above 1 000 V. However, the term medium-voltage (MV) is commonly used for distribution systems with voltages above 1 kV and generally applied up to and including 52 kV.
NOTE 2 Throughout this standard, the term "pressure" stands for "absolute pressure".
NOTE 3 Reference is also made to (Cigré Brochure 802, 2020).
NOTE 4 For further details on gases, e.g. ecotoxicology, also refer to the chemical database ECHA (www.echa.europa.eu), which takes the actual volume band into consideration.
NOTE 5 When reference to circuit-breakers is made, only gas circuit-breakers are of interest. When vacuum circuit breakers are of interest, they are explicitly mentioned.

At each end of the HV gas-insulated transmission line, a specific element may be used for the connection between the HV gas-insulated transmission line and other equipment like bushings, power transformers or reactors, cable boxes, metal-enclosed surge arresters, voltage transformers or GIS, covered by their own specification.
Unless otherwise specified, the HV gas-insulated transmission line is designed to be used under normal service conditions.
Note 1 to entry: In this international standard, the term "HV gas-insulated transmission line" is abbreviated to "GIL".
Note 2 to entry: In this international standard, the word "gas" means gas or gas mixture, as defined by the manufacturer.
Note 3 to entry: Examples of GIL applications are given:
- where all or part of the HV gas-insulated transmission line is directly buried; or
- where the HV gas-insulated transmission line is located, wholly or partly, in an area accessible to public; or
- where the HV gas-insulated transmission line is long (typically longer than to 500 m) and the typical gas compartment length exceeds the common practice of GIS technology.

SIST EN IEC 62271-202:2022(Main)
High-voltage switchgear and controlgear - Part 202: AC prefabricated substations for rated voltages above 1 kV and up to and including 52 kV (IEC 62271-202:2022)
EN IEC 62271-202:2022

This part of IEC 62271 specifies the service conditions, rated characteristics, general structural requirements and test methods of enclosed high-voltage prefabricated substations. These prefabricated substations are cable-connected to AC high-voltage networks with highest operating voltage up to and including 52 kV and power frequencies up to and including 60 Hz. They can be manually operated from inside (walk-in type) or from outside (non-walk-in type).They are designed for outdoor installation at locations with public accessibility and where protection of personnel is provided.
These prefabricated substations can be situated at ground level or partially or completely below ground level. The last are also called underground prefabricated substations.
In general, two types of prefabricated substations are considered in this standard:
- high-voltage switching prefabricated substations;
- high-voltage/low-voltage transformer prefabricated substations (step-up and step-down).
A high-voltage switching prefabricated substation comprises an enclosure containing in general the following electrical components:
- high-voltage switchgear and controlgear;
- auxiliary equipment and circuits.
A high-voltage/low-voltage transformer prefabricated substation comprises an enclosure containing in general the following electrical components:
- power transformers;
- high-voltage and low-voltage switchgear and controlgear;
- high-voltage and low-voltage interconnections;
- auxiliary equipment and circuits.
However, relevant provisions of this standard are applicable to designs where not all these electrical components exist (for example, a prefabricated substation consisting of power transformer and low-voltage switchgear and controlgear).
The listed electrical components of a high-voltage/low-voltage transformer prefabricated substation can be incorporated in the prefabricated substation either as separate components or as an assembly type CEADS according to IEC 62271-212.
This standard covers only designs using natural ventilation. However, relevant provisions of this standard are applicable to designs using other means of ventilation except the rated power of the prefabricated substation and associated class of enclosure (see 5.101), the continuous current tests (see 7.5) and all temperature rise related requirements, which would require an agreement between manufacturer and user.
NOTE IEC 61936-1 [1] provides general rules for the design and erection of high-voltage power installations. As well, it specifies additional requirements for the external connections, erection and operation at the place of installation of high-voltage prefabricated substations compliant with IEC 62271-202, which are regarded as a component of such installation. Non-prefabricated high-voltage substations, 483 are generally covered by IEC 61936-1 [1].
