VIBRATION AND BALANCE PROBLEMS IN FOSSIL PLANTS - INDUSTRY CASE HISTORIES.

The purpose of this report is to demonstrate some practical uses of vibration analysis through the presentation of actual field case histories. The case histories contained in the report include turbines, generators, fans, pumps and electric motors common to the utility industry. Each case history is divided into six sections: Definition of the Problem; Symptoms of the Problem; Test Data and Observations; Corrective Actions Taken; Final Results; Conclusions and Recommendations. In addition, several case histories involving the field balancing of turbines, generators and exciters have been included.
