CODIS PMU - portable vibration monitoring unit is again in action
Veski CoDiS-PMU (Portable Monitoring Unit) 16 channel device is again in action!
This time we measured vibrations, air gap and magnetic field on a 30 MW Francis unit. The unit suffered from pronounced magnetic unbalance. The PMU worked together with CoDiS-PDS (Portable Diagnostic System) software as a valuable diagnostic tool to help detect and correct rotor geometry issues. Our goal was to obtain an answer to the question about what should be done during the unit's overhaul.
