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. Keywords: cyclic duty, delamination, groundwall degradation, IEEE 1310, indirectly cooled machines, peaking duty, stator winding, thermal cycling. 517 $aIEEE Std 1310-2012 (Revision of IEEE Std 1310-1996): IEEE Recommended Practice for Thermal Cycle Testing of Form-Wound Stator Bars and Coils for Large Rotating Machines 517 $aIEEE Std 1310-2012 606 $aElectric generators$xTesting 606 $aGas-turbines$xTesting$xStandards 615 0$aElectric generators$xTesting. 615 0$aGas-turbines$xTesting$xStandards. 676 $a621.313 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a996280735103316 996 $aIEEE Std 1310-2012 (Revision of IEEE Std 1310-1996)$92576310 997 $aUNISA
