Current trends in design of pump-turbines have led into higher rotor-stator interaction (RSI) loads over impeller-runner.
These dynamic loads are of special interest having produced catastrophic failures in pump-turbines.
Determining RSI characteristics facilitates the proposal of actions that will prevent these failures.
Pressure measurements all around the perimeter of the impeller-runner are appropriate to monitor and detect RSI characteristics.
Unfortunately most installed pump-turbines are not manufactured with in-built pressure sensors in appropriate positions to monitor RSI.
For this reason, vibration measurements are the preferred method to monitor RSI in industry.
Usually vibrations are measured in two perpendicular radial directions in bearings where valuable information could be lost due to bearing response.
In this work, in order to avoid the effect of bearing response on measurement, two vibration sensors are installed rotating with the shaft.
The RSI characteristics obtained with pressure measurements were compared to those determined using vibration measurements.
The RSI characteristics obtained with pressure measurements were also determined using vibrations measured rotating with shaft.
These RSI characteristics were not possible to be determined using the vibrations measured in guide bearing.
Finally, it is recommended to measure vibrations rotating with shaft to detect RSI characteristics in installed pump-turbines as a more practical and reliable method to monitor RSI characteristics.
