About This Item
IEEE P1247/D5, Oct 2004 is a draft standard for interrupter switches for alternating current rated above 1000 volts. It focuses on the technical requirements needed to control and interrupt high-voltage AC circuits safely and consistently in power, energy, and industrial applications. For engineers, specifiers, and procurement teams, this document helps define performance expectations, design considerations, and testing priorities for equipment used in demanding electrical systems.
IEEE P1247/D5, Oct 2004 overview
This draft IEEE standard addresses interrupter switches intended for higher-voltage alternating current service, where reliable switching and interruption are critical to system operation. IEEE P1247/D5, Oct 2004 is relevant to equipment selection and engineering review because it helps frame how such devices should be built, rated, and evaluated for service above 1000 volts. In practice, it supports a common technical basis for design, verification, and comparison of products used in power-system applications.
Typical use cases
IEEE P1247/D5, Oct 2004 is typically consulted when specifying or reviewing interrupter switches for medium- and higher-voltage AC installations. That may include substation gear, industrial power distribution, utility switching arrangements, and other systems where interruption performance affects continuity and safety. It is also useful during procurement and engineering coordination when comparing device ratings, operating duty, and test requirements for equipment intended for power, energy, and industry applications.
Why this standard matters
This standard matters because interrupter switches in elevated-voltage AC systems must perform predictably under electrical stress. IEEE P1247/D5, Oct 2004 can help reduce ambiguity in design and acceptance decisions by providing a shared technical reference for ratings, performance expectations, and evaluation criteria. That consistency supports safer equipment selection, clearer supplier comparisons, and better control of operational risk in systems where interruption performance is closely tied to reliability.
