Full title and description

IEC/IEEE 62271-37-013:2021 Corrigendum 1 (2024) — High‑voltage switchgear and controlgear — Part 37‑013: Alternating‑current generator circuit‑breakers. This is an IEC/IEEE dual‑logo international standard that specifies ratings, performance, design and test requirements for three‑phase AC high‑voltage generator circuit‑breakers intended for installation between generator and transformer terminals (systems >1 kV up to 38 kV, 50/60 Hz).

Abstract

This document defines functional, electrical, mechanical and testing requirements for generator circuit‑breakers (GCBs), including requirements for operating mechanisms, auxiliary equipment and coordination with associated generator and transformer equipment. Corrigendum 1 (2024) issues official editorial/technical corrections to the 2021 edition.

Scope

The standard applies to three‑phase AC high‑voltage generator circuit‑breakers designed for indoor or outdoor installation on systems having nominal voltages above 1 kV and up to 38 kV and for operation at 50 Hz and 60 Hz. It is specifically intended for GCBs located between generator and transformer terminals and addresses requirements for applications with generators/transformers rated 10 MVA or more; smaller or pumped‑storage installations are treated as special applications and may need additional consideration. The standard also covers operating mechanisms and auxiliary equipment associated with GCBs.

Key topics and requirements

• Ratings and classification for voltage, current, breaking capacity and making capacity relevant to generator fault conditions.
• Electrical performance: short‑circuit breaking requirements, making requirements, dielectric and insulation coordination for generator‑side installations.
• Mechanical requirements: endurance, mechanical operation, spring and hydraulic/mechanical drives, kinetic energy and structural integrity under fault duty.
• Operating mechanisms and auxiliary systems: control, interlocks, closing/tripping devices, auxiliary power, and monitoring provisions.
• Testing and type tests: routine, type and special tests for dielectric, thermal, mechanical and electrical performance under generator conditions.
• Coordination with generator and transformer protection and requirements specific to applications ≥10 MVA; guidance for special applications (smaller units, pumped‑storage).
• Documentation, marking and instructions for safe transport, installation, operation and maintenance.

These topic areas and requirements are established to ensure the safe, reliable operation of GCBs under generator fault and normal operating conditions.

Typical use and users

Primary users include power plant designers and engineers, switchgear manufacturers, utility specifiers and procuring authorities, testing and certification laboratories, and electrical consultants responsible for generator protection and substation design. The standard is used to specify GCB performance in procurement documents, to design and test equipment, and to guide factory and site acceptance testing.

Related standards

IEC/IEEE 62271‑37‑013 is part of the IEC/IEEE 62271 series. It is intended to be used in conjunction with IEC 62271‑1 (general definitions and common requirements for high‑voltage switchgear and controlgear). Other related publications include standards and IEEE guides on circuit‑breaker ratings, testing and generator/transformer interfaces (for example IEC 60034 for rotating electrical machines and relevant IEEE C37 series standards on circuit breakers and testing).

FAQ

Q: What is this standard?

A: IEC/IEEE 62271‑37‑013:2021 (with Corrigendum 1, 2024) is the international dual‑logo standard that sets requirements for three‑phase AC high‑voltage generator circuit‑breakers used between generators and transformers on systems above 1 kV up to 38 kV.

Q: What does it cover?

A: It covers ratings, electrical and mechanical performance, type and routine testing, insulation coordination, operating mechanisms, auxiliary equipment, documentation and application guidance—particularly for installations with generator/transformer ratings of 10 MVA and above. Special applications (smaller units, pumped storage) may require supplemental rules.

Q: Who typically uses it?

A: Manufacturers of generator circuit‑breakers, power utilities, plant designers and engineers, test laboratories, procurement/specification teams and consultants involved in high‑voltage power plant and substation projects.

Q: Is it current or superseded?

A: The 2021 second edition is the current base document; Corrigendum 1 was issued in 2024 to correct/clarify specific items. Users should apply the 2021 edition together with the 2024 corrigendum.

Q: Is it part of a series?

A: Yes — it is one part of the IEC/IEEE 62271 series (high‑voltage switchgear and controlgear). It is intended to be used alongside the general requirements in IEC 62271‑1 and other parts of the 62271 family and relevant IEEE C37 documents.

Q: What are the key keywords?

A: Generator circuit‑breaker, GCB, high‑voltage switchgear, alternating current, ratings, type tests, insulation coordination, operating mechanism, IEC/IEEE 62271‑37‑013, corrigendum 2024.
