Abstract
Undesirable internal changes in a running turbine are diagnosed by monitoring the dynamic pressure of the stream of fluid and the structure-borne vibration of the stationary shell. Incipient erosion of blades, material deposit buildup, and other abnormalities are detected by analyzing the dynamic pressure and vibration signal utilizing several signal processing techniques. A better maintenance schedule can be derived, this also serves as a turbine efficiency monitor.
