Until recent revisions, the basic procedures and standards in use were written over 25 years ago. Since the s, motor windings have encountered many changes in their design and manufacture.
In order to address this methodology, a calculation method was developed to determine temperature increases in the last stator package.

Understanding water treeing mechanisms in the development of diagnostic test methods. Power uprates pose a threat to electrical generators due to possible parasite effects that can develop potential failure sources with catastrophic consequences in most cases. Topics Discussed in This Paper.
Stone Published in IEEE Transactions on Industry Applications IEEE standards and test procedures are widely used by motor and generator vendors and users to commission windings in new machines, as well as evaluate the condition of the winding insulation in operating machines.
