IEEE P62271-37-013:2015 D13.4

IEEE P62271-37-013:2015 D13.4 is an approved draft international standard for high-voltage switchgear and controlgear, with a specific focus on alternating-current generator circuit-breakers. It provides technical guidance for equipment used to connect and protect generator circuits, where switching duty, interruption performance, and system coordination are critical. For engineering, procurement, and compliance work, this standard helps define a common reference for design and evaluation in power, energy, and industry applications.

What is IEEE P62271-37-013:2015 D13.4?

This technical document belongs to the IEEE P62271 series and addresses alternating-current generator circuit-breakers within high-voltage switchgear and controlgear. IEEE P62271-37-013:2015 D13.4 is intended to support consistent requirements for the equipment’s construction, ratings, and operational expectations in generator-circuit applications. It is especially relevant where switching reliability, fault interruption, and integration with generator systems must be considered together, making it a practical reference for specification and review.

Where is IEEE P62271-37-013:2015 D13.4 used?

IEEE P62271-37-013:2015 D13.4 is typically used in power generation and electrical infrastructure projects that involve generator circuit-breakers at medium- or high-voltage levels. It is relevant to engineers working on generator interconnection, switchgear assemblies, and controlgear selection for industrial plants, utility installations, and similar heavy electrical systems. The standard may also support design reviews, tender documents, and equipment qualification where alternating-current generator protection and switching performance must be aligned.

Why is IEEE P62271-37-013:2015 D13.4 important?

This standard matters because generator circuit-breakers must perform reliably under demanding operating and fault conditions. IEEE P62271-37-013:2015 D13.4 helps bring consistency to design expectations, testing approach, and procurement language for equipment used in high-voltage generator applications. That can reduce specification ambiguity, improve compatibility between systems, and support safer operation. For inactive standards such as this one, it also provides useful technical reference context for legacy equipment, documentation checks, and engineering comparisons.
