The Evolution of RMS Technology
Key Finding from 28 years of RMS Operation
- Monitoring the full height of the stator is not necessary.
- Detrimental electrical conditions within a hydro generator stator can be detected by monitoring only the ends of the core and adjacent portions of the endwinding from the vantage point of the rotor
Why?
These “end regions” of the stator are where unbalanced forces exist that often
cause component failure primarily due to:
- Eddy Current (inductive) heating from fringing magnetic fields (flux)
- Non uniform cooling air flow
- Limited mechanical support of endwinding components
