scope:

The general parameters for this guide apply to 50 Hz or 60 Hz synchronous generators driven by reciprocating engines, steam turbines, combustion turbines, and hydro-turbines. The guide generally applies to the stator and rotor of generators with rated outputs of 1 MVA and above. The guide does not address machine auxiliaries or the excitation system.

Purpose

This guide will provide the generator Owner with insight into the considerations that are necessary when rewinding or refurbishing a generator. Particular emphasis is placed on the complete rewind of each of the components of the stator and rotor.
