Discussion of vibration patterns and thechnical theory on 3 case studies.

1. A steam turbine generator experiences synchronous dry rub during normal operation which is detected early using online system1.
2. A gas turbine generator ungoing in-situ balancing using portable vibration analyser ADRE 408 (one shot balancing).
3. A CID FAN experiences high vibration during loading (rubbing).
