Hydro unit monitoring webinar series – Part 4: Monitoring the turbine (Francis, Kaplan)

 
The hydro unit monitoring webinar series is intended to help end-users and service providers to better understand the monitoring techniques and to improve the reliability of implementing an effective condition monitoring approach for hydro machines in your power station. In Part 4 we will look at typical failure modes for the hydro unit turbine and its nearby components; stay vanes, guide vanes, distributor, draft tube. A range of time-proven, best-practice monitoring techniques will then be presented for detecting and diagnosing faults, such as: • Francis turbine labyrinth seals • Kaplan turbine blade clearance • Blade erosion • Water hammer • Vortex turbulence • Von Karman turbulence • Cavitation A description of the sensor technology is also given, as well as a basic review of applicable international standards for the monitoring techniques.
