P1310
Recommended Practice for Thermal Cycle Testing of Form-Wound Stator Bars and Coils for Large Rotating Machines
This recommended practice describes a test procedure used for individual form-wound bars/coils for rotating machines typically rated 10 kV or more at 50 Hz or 60 Hz that are subjected to many transitions from no-load to full-load current during normal operations, and where rapid load variations are typical. Only the thermal cyclic degradation due to delamination of the groundwall insulation and debonding of the groundwall insulation from the conductor stack are addressed by this test. Examples of indirectly (conventionally) cooled machine types that typically experience rapid load transitions include: - Combustion turbine generators - Pumped storage or peaking duty hydrogenerators - Synchronous condensers - Cyclic duty water pump motors Various pass/fail criteria are defined, to facilitate agreement between the user and the manufacturer on the criteria that apply in a specific circumstance, prior to the commencement of testing.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.

IEEE Recommended Practice for Thermal Cycle Testing of Form-Wound Stator Bars and Coils for Large Rotating Machines
This procedure is intended for form-wound bars/coils for rotating machines rated 10 kV or more at 50 Hz or 60 Hz that are subjected to many transitions from no-load to full-load current during normal operations, and where rapid load variations are typical. Only the thermal cyclic degradation within the groundwall insulation and/or the conductor package and delamination of the groundwall insulation from the conductor are addressed by this test. The procedure is applicable to indirectly-cooled machine types such as: -- combustion turbine generators -- pumped storage or peaking duty hydrogenerators -- synchronous condensers -- cyclic duty water pump motors Various pass/fail criteria are presented, and the ones that apply in a specific circumstance must be agreed between user and manufacturer prior to commencement of testing
