Figure 6 - Prognostic and Health Management of Active Assets in Nuclear Power Plants

New diagnosis result summary page created by the Diagnostic Advisor when C 2 H 2 level reaches Watch List As monitoring continues, the FW-PHM's Diagnostic Advisor polls the Oracle Database at regular intervals to generate a series of diagnoses as shown in Figure 7. For the example presented in this paper, the Diagnostic Advisor polled the Oracle Database every minute. Observe that the updated Diagnosis Result Page presents the diagnosis update history and updated possible diagnosis with current query values. With time, Possible Diagnosis has been updated and now Paper Insulation Degradation: Thermal is identified as the most likely diagnosis based on the current C 2 H 2 , CO, and CO 2 /CO ratio. Also, observe that the Diagnostic Advisor has updated the Troubleshooting Advice, suggesting the inclusion of top insulating oil temperature information if possible (i.e., Time at Excess Temperature) to further refine the diagnosis.
