Revision Standard – Inactive-Reserved. 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<\/p>\n
