About This Item
IEEE P1665/D21, Aug 2022 is a draft technical guide for the rewind of synchronous generators rated 1 MVA and above, covering both 50 Hz and 60 Hz machines. It is relevant to power, energy, and industry applications where generator rewind work must preserve electrical performance, insulation integrity, and operating reliability. By setting a focused framework for this repair activity, IEEE P1665/D21, Aug 2022 helps support consistent engineering decisions during maintenance and refurbishment.
IEEE P1665/D21, Aug 2022 overview
This draft guide addresses the technical considerations involved when rewinding synchronous generators, including units used in industrial plants, utility-connected systems, and other rotating machine installations. IEEE P1665/D21, Aug 2022 is centered on generator rewind practice rather than general machine design, making it useful for planning, evaluating, and executing repair work. The document helps frame expectations for materials, workmanship, and performance restoration so that rewound machines can be assessed against a consistent engineering basis.
Typical use cases
IEEE P1665/D21, Aug 2022 is commonly used when a synchronous generator requires stator or rotor rewind after aging, insulation deterioration, electrical fault damage, or repeated service stress. It is relevant to maintenance teams, rewind shops, and engineering groups working on 50 Hz or 60 Hz generators in power stations, captive power systems, and heavy industrial facilities. The guide may also support inspection planning, repair specification development, and acceptance review after refurbishment work on machines rated 1 MVA and above.
Why this standard matters
Rewind work on large synchronous generators has direct impact on reliability, safety, and long-term operating cost, so a focused guide is important. IEEE P1665/D21, Aug 2022 supports more consistent repair decisions by helping define what should be checked, documented, and controlled during the rewind process. That can reduce the risk of uneven workmanship, premature failure, and performance loss after return to service. For buyers and engineers, it also provides a clearer basis for procurement, quality review, and technical acceptance.
