Summary
Loss of mechanical integrity of stator windings resulting in amplified vibration, both in the endwinding and slot area, has been a concern on large turbogenerators which can lead to failure in service.
This Technical Brochure summarizes the results and conclusions of a survey about experiences of stator winding support systems including design, detected problems, evaluation techniques, RCA, repairs and design modifications.
