Abstract
In situ vibration measurements are carried out on a a typical steam turbo-generator (TG) unit at the West Burton Power Plant UK during the steady state operation. A typical phenomenon of appearance of low frequencies in band of 7–12 Hz is observed mainly related to the vibration measurements on low pressure (LP) turbines bearing pedestals. This band of frequency observed to be modulating with vibration at the machine RPM (50 Hz) and its higher harmonics. The paper summaries the possible causes for such dynamic behaviour.
