IEEE 62271-37-013-2015

62271-37-013-2015 is a technical standard for alternating-current generator circuit-breakers, providing guidance for design and related requirements in power, energy, and industrial applications. It helps define how these devices are specified, assessed, and applied where generator protection and switching performance are critical. For engineers, purchasers, and compliance teams, this standard supports clearer expectations around equipment suitability, testing, and reliable operation in generator-connected systems.

What is 62271-37-013-2015?

62271-37-013-2015 addresses AC generator circuit-breakers within the broader 62271 series for high-voltage switchgear and controlgear. It is concerned with the technical requirements and application context for circuit-breakers used to connect, protect, and isolate generators under operating conditions typical of power systems. As a specification, it is relevant where performance, coordination, and switching duty must be defined with care. The standard is superseded, but it remains useful as a reference for legacy equipment and historical compliance needs.

Where is 62271-37-013-2015 used?

This standard is mainly used in generator switchgear arrangements, power plant interfaces, and other electrical installations where alternating-current generators are connected to a network through circuit-breakers. It is relevant to utilities, industrial power generation, and large rotating-machine applications that rely on controlled interruption and isolation. In practice, 62271-37-013-2015 helps frame requirements for generator bays, switchgear assemblies, and related protection schemes where switching behavior and system coordination are central to safe operation.

Why is 62271-37-013-2015 important?

Because generator circuit-breakers must perform under demanding electrical conditions, 62271-37-013-2015 matters for safety, consistency, and procurement accuracy. It helps buyers and specifiers compare equipment against a recognized technical basis instead of relying on general descriptions alone. For manufacturers and project teams, it can support design control, testing, and risk reduction when defining ratings and application limits. Even as a superseded document, it can still be important for documentation review and legacy system support.
