Figure 20. Typical Generator Metering Panel10.2.7Generator Vibration and Temperature Monitoring

X and Y proximity probes are mounted in the generator exciter and driven-end bearings. These probes are monitored continuously by the control system. Alarm and shutdown levels are set to protect the generator from excessive vibration levels

Resistance temperature devices (RTDs) are mounted in the generator exciter and driven end bearings. Two RTDs are also imbedded in each of the three stator-winding phases. One RTD is connected to the control system and the other is provided as a spare. Alarm and shutdown levels are set to protect the generator from excessive temperature levels.

10.2.8Redundant Combined Generator Control Module (Optional)

A second CGCM can be provided to function as a hot backup to the primary CGCM. The system is configured for automatic transfer to the second CGCM in the event the primary CGCM fails. All control, protection, and monitoring features of the primary CGCM are duplicated in the second CGCM. Control can also be manually transferred between the CGCMs.
