This guide describes methods which may be used to evaluate the condition of stator cores of AC electric machines including generators, motors, and synchronous condensers, and summarizes background information relevant for the informed application of these methods.
This guide is not intended to provide detailed inspection, testing, and maintenance procedures. Other IEEE standards and references related to stator core evaluations and repairs are listed in Clause 2, "Normative References".
The methods outlined herein are generally applicable to machines rated 1 MVA (1340 HP) and higher. However, these methods may be applicable to units of lower rating.
