Air Gap Monitoring
Large low speed hydro-generators have a very small air gap stator bore diameter ratio making it impossible for elements to be perfectly centred during the assembly process. This results in... [detail]
Endwinding Vibration Monitoring
Current operating practices impose severe thermal and mechanical stresses on the rotors and stators of large pump storage hydro-generators. One such practice involves multiple daily run-ups and... [detail]
Shaft and Bearing Vibration Monitoring
Shaft radial vibration amplitude and radial position are primary indicators of the overall mechanical condition of rotating machinery. It is possible to detect many machine malfunctions... [detail]
Ring Motors and Rotating Air Gap Monitoring
Ring motor drive mills are loaded with several hundred tons of ores. This enormous mass in rotation generates forces acting directly on the main bearings supporting the mill. Furthermore, the... [detail]
Water Gap Monitoring
The runner blade clearance sensor measures distance variations between the turbine blade tip in relation to the throat ring surface. The surface of the turbine blade tip consists of NiCr... [detail]
