| Abstract: | From the model and prototype test result, hydraulic f au lts in francis turbines were introduced. The characteristics of hydraulic vibrat ions in draft tubes and variation of vibrations with operation conditions were s tudied. A method for monitoring the hydro-vibration in draft tube and diagnosin g the fault based on the frequency and amplitude of hydro-vibration was introdu ced. |
