Thrust bearing monitoring of vertical hydro-turbine-generators

Earlier this year Ryszard Nowicki and Nikolay Morozov presented this paper at the First World Congress of Condition Monitoring in London. The paper provides detailed technical analysis and recommends best practices for improving reliability of hydro turbine generators.

Executive Summary: 
A serious thrust bearing failure of a high power vertical hydro-generator is described. Analysis of the applied monitoring and protection system for the thrust bearings is provided. Slow response time of the protection system is investigated. A guideline for the more efficient protection system is provided.
