Title: Vibration Characteristics of Hydro Plant Equipment
Abstract: This paper provides practical experiences and vibration data of slow speed hydro turbine -generators and their associated structures, such as the penstock and draft tube. The benefits of using vibration monitoring as part of the predictive maintenance program for hydro plants are documented in different case histories. Typical vibration and noise data of turbine runner cavitation, mechanical hydraulic unbalance, misalignment, penstock resonance, draft-tube resonance, draft tube surging due to pressure pulsation, rough-zone operations, worn seals and generator 120 Hz core resonance are displayed and analyzed.
