About This Item
IEEE 1665-2024 is the IEEE Guide for Rewind of Synchronous Generators, 50 Hz and 60 Hz, Rated 1 MVA and Above. It addresses practical considerations for rewinding large synchronous generator windings, helping guide engineering decisions that affect insulation, materials, electrical integrity, and long-term performance. For owners, repair facilities, and technical teams, this standard supports more consistent rewind work on high-value rotating machines used in power and industrial applications.
Overview of IEEE 1665-2024
This standard provides guidance for rewind activities on synchronous generators operating at 50 Hz and 60 Hz with ratings of 1 MVA and above. IEEE 1665-2024 is relevant where generator winding repair or replacement must preserve electrical characteristics and serviceability after overhaul. The document is useful in contexts where design details, winding construction, and workmanship need to be handled carefully to reduce the risk of premature failure and to support dependable return to operation.
Typical use cases
IEEE 1665-2024 is commonly used during planned outages, major repairs, and refurbishment of synchronous generators in utility, industrial, and infrastructure settings. It can support decisions for rewind specifications, shop procedures, and inspection checkpoints when stator or rotor windings require replacement or restoration. The guide is also helpful for maintenance contractors, engineering teams, and procurement staff defining technical requirements for generator overhaul projects where electrical performance and rebuild consistency are important.
Why it matters
Rewinding a synchronous generator is a high-impact repair, and the quality of that work can directly influence reliability, efficiency, and future maintenance needs. IEEE 1665-2024 helps bring structure to these projects by giving a technical reference for consistent rewinding practices. That can improve compliance with internal specifications, reduce ambiguity between owner and repair shop, and support better control of insulation, workmanship, and test outcomes on critical rotating equipment.
