Repair the Hydro Generator by Cutting Out Stator Winding Bars/Coils

Published May 8th, 2019 IRMC 2019, Igor Chichkin

Why generator stator winding fails?
  • Poor coil/bar manufacturing quality
  •  Poor coil/bar installation quality
  •  Winding stresses during generator operation
Sources of stress in the machine that lead to stator winding deterioration :
  • Thermal – heat generated by the working generator ( thermal cycling)
  • Mechanical – caused by machine vibration
  • Electrical – caused by voltage stress
  • Chemical stresses – caused by the breakdown of materials, insulation “glue”
  • epoxy resin) and other components over time.
  • Environmental factors
