(Main)High-voltage switchgear and controlgear - Part 111: Automatic circuit reclosers and fault interrupters for alternating current systems up to 38 kV
High-voltage switchgear and controlgear - Part 111: Automatic circuit reclosers and fault interrupters for alternating current systems up to 38 kV
IEC 62271-111:2012(E) applies to all overhead, pad mounted, dry vault and submersible single or multi-pole alternating current automatic circuit reclosers and fault interrupters for rated maximum voltages above 1 000 V and up to 38 kV. This second edition cancels and replaces the first edition, published in 2005, and constitutes a technical revision. The main changes with respect to the previous edition are as follows:
a) addition of exclusion of devices with dependent manual operation to 1.1;
b) harmonization of the amplitude factor kaf used for calculating the TRV for cable connected systems consistent with recent harmonization of the circuit-breaker standards between IEEE and IEC;
c) deletion of requirements for radio influence voltage (RIV) tests;
d) addition of specifications and ratings to cover the cutout recloser and its special requirements.
This standard has been jointly revised by Switchgear Committee of the IEEE Power and Energy Society, in cooperation with subcommittee 17A: High-voltage switchgear and controlgear with reference to IEEE Std C37.60-2012(E).
This publication is to be read in conjunction with IEC 62271-1:2007.
General Information

Overview
IEC 62271-111:2012 is the international standard that specifies requirements, tests and ratings for automatic circuit reclosers (ACRs) and fault interrupters for single- or multi-pole alternating‑current systems with rated maximum voltages above 1 000 V and up to 38 kV. It covers overhead, pad‑mounted, dry‑vault and submersible reclosers and fault interrupters. Edition 2.0 (2012) is a technical revision harmonized with IEEE Std C37.60‑2012 and is intended to be read in conjunction with IEC 62271‑1:2007.
Key Topics and Technical Requirements
- Scope and service conditions: Defines normal and special service conditions (altitude, pollution, temperature, vibration, wind) for indoor and outdoor installations.
- Ratings and characteristics: Requirements for rated voltage, frequency, rated normal current, rated short‑time and peak withstand currents, rated interrupting and making currents, and rated operating sequences.
- Transient Recovery Voltage (TRV): Updated TRV calculation guidance, including harmonization of the amplitude factor (kaf) for cable‑connected systems consistent with IEEE/IEC circuit‑breaker harmonization.
- Design and construction: Enclosure protection (IP/IK), insulation and creepage distances, liquid/gas tightness, tank construction for submersible/dry‑vault units, stored energy and power operation provisions, nameplates and position indication.
- Type tests and routine tests: Dielectric tests, temperature‑rise, short‑time and peak withstand current tests, tightness tests, EMC testing, auxiliary/control circuit tests. Note: radio influence voltage (RIV) test requirements were deleted in this edition.
- Special device types: Addition of specifications and ratings for cutout reclosers and their special requirements.
- Operational mode exclusions: Excludes devices with dependent manual operation (per clause 1.1).
Practical Applications and Who Uses This Standard
IEC 62271‑111 is essential for:
- Utilities and distribution network operators specifying ACRs and fault interrupters for overhead and underground distribution systems.
- Manufacturers and designers developing reclosers, cutout reclosers, and submersible fault interrupters to meet international test and safety benchmarks.
- Test laboratories performing type and routine testing (dielectric, TRV, short‑circuit, EMC).
- Protection and relay engineers, procurement/specification teams, and standards compliance officers ensuring equipment interoperability and safety up to 38 kV.
Typical applications include automated fault isolation and service restoration, rural and urban distribution feeders, pad‑mounted transformer protection, and submarine/submersible installations.

IEC 62271-111:2012は、高電圧スイッチギアおよび制御機器に関する非常に重要な標準であり、その範囲は、最大電圧が1,000 Vを超え38 kVまでの交互電流自動回路復帰装置および故障中断器に適用されます。この標準は、2005年に発行された初版を廃止し、技術的な改訂を含む第二版として発表されました。 この標準の強みは、以下のような主な変更点に見られます。まず、1.1項において手動操作を依存する装置の除外が追加され、より特定の適用範囲が定義されました。これにより、使用条件や安全基準がより明確になりました。 さらに、ケーブル接続システム向けの過渡電圧（TRV）の計算に使用される振幅係数kafが最近のIEEEおよびIECの回路遮断器標準に合わせて調整され、国際的な整合性が確保されています。この点も、国際基準に照らしたときの信頼性を高める要因となります。 RIV（無線影響電圧）試験に関する要件が削除されたことは、標準が現代の技術的要求に適応していることを示しています。また、カットアウトリクロサーおよびその特殊要件をカバーするための仕様や格付けが追加され、ユーザーに対して新たな導入を可能にしています。 この標準は、IEEE電力・エネルギー学会のスイッチギア委員会と、IEEE Std C37.60-2012(E)に関連する高電圧スイッチギアおよび制御機器に関するサブコミッティー17Aによって共同改訂されており、これにより専門的な知見と業界の最新のニーズを反映しています。 IEC 62271-111:2012は、IEC 62271-1:2007と合わせて読むことが推奨されており、標準化されたプロセスやデバイスの適切な使用を促進するためのガイドラインとして機能します。
La norme IEC 62271-111:2012 est essentielle pour la normalisation des dispositifs de réarmement automatique et des interrupteurs de défaut dans les systèmes de courant alternatif allant jusqu'à 38 kV. Son champ d'application est très pertinent car il couvre une large gamme d'équipements, y compris les réarmateurs automatiques et les interrupteurs de défaut à un ou plusieurs pôles, adaptés aux environnements aériens, montés sur socle, dans des voûtes sèches ou submersibles pour des tensions de service dépassant 1000 V. Une des forces majeures de cette norme est sa révision technique par rapport à l'édition précédente de 2005. Les ajouts et modifications qu'elle comprend contribuent à une meilleure harmonisation et normalisation des dispositifs. Par exemple, l'exclusion explicite des dispositifs à fonctionnement manuel dépendant et l'harmonisation du facteur d'amplitude kaf pour le calcul de la tension de rétablissement transitoire (TRV) sont des améliorations significatives. Ces mises à jour garantissent que les utilisateurs peuvent se conformer aux exigences les plus récentes des normes des disjoncteurs établies par l'IEEE et l'IEC. De plus, la suppression des exigences relatives aux tests de tension d'influence radio (RIV) simplifie le processus de certification, permettant ainsi une mise sur le marché plus rapide de nouveaux équipements. L'ajout de spécifications et de notations pour les réarmateurs à coupure couvre également des besoins spécifiques qui n'étaient pas suffisamment abordés auparavant. Cette norme, élaborée en coopération avec le comité d'équipement de commutation de l'IEEE Power and Energy Society, démontre une approche collaborative qui renforce sa crédibilité et son adoption dans le secteur. En outre, elle doit être lue en conjonction avec l'IEC 62271-1:2007 pour une compréhension complète des exigences liées aux équipements de commutation haute tension. En résumé, l'IEC 62271-111:2012 joue un rôle crucial dans le cadre réglementaire des équipements de haute tension, enrichissant les pratiques de sécurité et d'efficacité dans les systèmes électriques modernes.
