Full title and description

St IEC 62271-102-2022 — High‑voltage switchgear and controlgear — Part 102: Alternating current disconnectors and earthing switches. This entry refers to the consolidated/extended 2022 edition (IEC 62271-102:2018 + Amendment 1:2022 / EXV or CSV), a technical revision that consolidates the 2018 edition with the 2022 amendment and related referenced content for users of disconnectors and earthing switches.

Abstract

This standard specifies definitions, ratings, design, testing and performance requirements for alternating‑current disconnectors and earthing switches intended for indoor and outdoor installations with nominal voltages above 1 000 V and frequencies up to 60 Hz. It covers operating devices, auxiliary equipment and gives normative/optional tests and verification procedures to ensure safe, reliable switching and earthing operations in high‑voltage networks.

Scope

This part of IEC 62271 applies to alternating current disconnectors and earthing switches designed for indoor and outdoor installations for nominal voltages above 1 000 V and service frequencies up to and including 60 Hz. It also applies to their operating devices and auxiliary equipment. Additional requirements for devices installed in enclosed switchgear are covered in other parts of the 62271 series. The document excludes disconnectors where a fuse is an integral part and is also applicable to switching devices that include disconnecting and/or earthing functionality in addition to other functions.

Key topics and requirements

• Definitions, classifications and ratings (voltage, current, making/breaking capacity, short-time withstand, frequency and environmental conditions).
• Design requirements for main and earthing contacts, insulating supports, clearances and creepage distances for indoor/outdoor use.
• Operational and mechanical requirements: endurance, mechanical operation sequences, interlocks, manual and motorized operation modes.
• Type and routine testing: dielectric tests, temperature rise, thermal stability, mechanical endurance, and short‑circuit performance where applicable.
• Safety and earthing requirements, auxiliary circuits, control and monitoring interfaces, and marking / documentation requirements.
• Specific provisions for devices incorporated into enclosed switchgear and guidance on interfacing with other 62271 series parts.

Typical use and users

Manufacturers of high‑voltage disconnectors and earthing switches, OEMs of switchgear, utilities, transmission and distribution engineers, testing and inspection laboratories, procurement specialists and certification bodies use this standard to specify, design, test and verify equipment for power system switching and earthing applications. It is also used by system integrators and consultants specifying equipment for substations and industrial high‑voltage installations.

Related standards

Commonly referenced companion documents include IEC 62271-1 (common specifications for high‑voltage switchgear and controlgear), IEC 62271-200/201/203 (requirements for enclosed switchgear and related equipment), and other parts of the 62271 series that address circuit-breakers, switch-disconnectors and supplementary tests. National adoptions (EN/IEC, NEN, DS/EN, etc.) and consolidated or extended (EXV/CSV) publications are also available for local use.

FAQ

Q: What is this standard?

A: It is the IEC international standard that sets requirements for alternating‑current disconnectors and earthing switches used in high‑voltage power systems; the 2022 consolidated/exv edition brings together the 2018 edition and the 2022 amendment for user convenience.

Q: What does it cover?

A: Definitions, ratings, construction and design requirements, operational/mechanical requirements, type and routine tests, safety and marking, and requirements for auxiliary equipment and interfaces for disconnectors and earthing switches for voltages above 1 kV up to high‑voltage network levels.

Q: Who typically uses it?

A: Equipment manufacturers, utilities, substation designers, test laboratories, certification bodies, procurement teams and consultants involved in HV switchgear selection, testing and compliance verification.

Q: Is it current or superseded?

A: The 2022 consolidated/EXV edition is the current consolidated form (it consolidates the 2018 edition with Amendment 1:2022). It cancels and replaces the earlier 2001 first edition and its subsequent amendments; users should check national adoptions for local dates of validity.

Q: Is it part of a series?

A: Yes — IEC 62271 is a multipart series covering high‑voltage switchgear and controlgear (for example, 62271-1, -102, -200, -201, -203, etc.), where -102 specifically addresses disconnectors and earthing switches and other parts provide common rules and requirements for enclosed switchgear and different device types.

Q: What are the key keywords?

A: Disconnectors; earthing switches; high‑voltage switchgear; IEC 62271; testing; ratings; mechanical endurance; safety; consolidated 2022 edition.
