Two recent developments in monitors for large turbine generators

Two instruments that can be used to monitor the generator stator end-windings and the shaft potential of turbine-generator systems are described. The authors' experience with the fiber-optic vibration monitor is described, along with their limited experience with the active shaft grounding syst...

Zusammenfassung:Two instruments that can be used to monitor the generator stator end-windings and the shaft potential of turbine-generator systems are described. The authors' experience with the fiber-optic vibration monitor is described, along with their limited experience with the active shaft grounding system. The benefits of integrating these monitors, and others, into an online artificial-intelligence-based diagnostic system are discussed.< >
