REDUNDANT INDICATION WHICH WILL VERIFY ALARM:
o INDICATED ECCENTRICITY FOR TURBINE ROTOR (TB-346-KI) ON TGF PANEL.
o ECCENTRICITY INDICATOR (TB-469-ZI) ON VMC-1 LOCATED IN TEST INSTRUMENT CALIBRATION ROOM.
i OPERATOR ACTIONS FOR A VALID ALARM:
o REDUCE TURBINE LOAD.
o IF TURBINE IS OFF LINE WITH GLAND STEAM APPLIED, NOTIFY SECONDARY PLANT OPERATOR TO PLACE ON TURNING GEAR.
DISCUSSION:
ROTOR ECCENTRICITY IS A MEASURE OF HOW MUCH THE TURBINE SHAFT IS BOWED. IT IS CAUSED BY UNEVEN HEATING OF THE TURBINE SHAFT AND USUALLY ONLY OCCURS DURING TURBINE STARTUP OR SHUTDOWN AND WHEN THE TURBINE IS NOT ROTATING.
Tl:E BOWING OF THE RO10R IS RECORDED CONTINUOUSLY FROM TURNING GEAR SPEED l
TO APPROXIMATELY 600 RPM. ABOVE 600 RPM THE VIBRATION INSTRUMENTS ARE USED TO INDICATE ROTOR ANOMALIES.

INDICATORS LOCATED IN TEST INSTRUMENT CALIBRATION ROOM.
l I
OPERATOR ACTIONS FOR A VALID ALARM:
o REDUCE TURBINE HEATUP RATE.
l DISCUSSION:
DIFFERENTIAL EXPANSION REFERS TO THE RELATIVE LENGTHS OF THE TURBINE ROTOR-l COMPARED TO THE TURBINE CASING. EITHER A LONG OR SHORT CONDITION CAN CAUSE TURBINE DAMAGE IF CONTACT OCCURS. THE CONDITION IS CAUSED BY UNEVEN HEATUP OF TURBINE COMPONENTS AND CAN BE CORRECTED BY SLOdING THE HEATUP RATE.

o REDUCE TURBINE GENERATOR LOAD AND INVESTIGATE CAUSE OF THRUST BEARING NOT CONTROLLING ROTOR POSITION.
o IF TURBINE IS TRIPPED BY lHE THRUST BEARING TRIP DEVICE THEN INSPECT THRUST BEARING COMPONENTS.
DISCUSSION:
THE ROTOR POSITION INSTRUMENT MEASURES THE RELATIVE POSITION OF THE ROTOR THRUST COLLAR TO THE THRUST-BEARING SUPPORT. SMALL CHANGES IN ROTOR POSITION CAN OCCUR WITH CHANGING ELECTRICAL LOAD. ANY WEAR ON THE THRUST SHOES RESULTS IN A MOVEMENT OF THE ROTOR AND IS RECORDED ON TB-119-ZIR.

o NOTIFY TURBINE BUILDING OPERATOR TO INVESTIGATE RF MONITORING CABINET.
o NOTIFY SYSTEM ENGINEER TO C0f9ARE WITH OTHER KNOWN DATA.
o REFER TO OP-701.
DISCUSSION:
THIS ALARM SERVES AS AN EARLY WARNING OF A GENERATOR FAILURE SUCH AS INSULATION BREAKDOWN AND/0R CAS SPACE IMPURITIES THAT MAY HAVE ENTERED THE GAS SPACES.
THE SYSTEM CONSISTS OF FOUR DETECTORS (ONE FOR EACH PHASE AND ONE FOR THE
- 8 BEARING) WHICH ARE MONITORED INDIVIDUALLY. THE SYSTEM CYCLES THROUGH ALL FOUR POINTS, AND IF ONE EXCEEDS THE ALARM VALUE THE ALARM IS SOUNDED.
THE SYSTEM ENGINEER CAN ASSIST IN DETERMINING IF A VALID CONDITION EXISTS IN THE GENERATOR OR IF THE RF MONITORING EQUIPMENT IS FAILED.

o PHASE BUS DUCT AIR FLOW AS SENSED BY TB-338-FS.
REDUNDANT INDICATION WHICH WILL VERIFY _ ALARM:
o PHASE BUS DUCT BLOWER FAN %T RUNNING WITH SWITCH IN AUTO AND THE GENERATOR FIELD BREAKER CAiD EVENT POINT 1645 OR 1655.
OPERATOR ACTIONS FOR A VALID ALARM:
o IF-FORCED COOLING HAS BEEN LOST, THEN IMMEDIATELY REDUCE LOAD TO < THE SELF COOLED RATING OF 10,000 AMPS AS INDICATED ON THE GENERATOR AMPS DIAL INDICATOR ON THE TGF PANEL.
l o MAINTAIN THE-DUCT TEMPERATURE < 151* F BY REDUCTION IN GENERATOR OUTPUT.
i AND TRANSFERRING LOADS FROM THE AUXILIARY TRANSFORMER.
o NOTIFY SECONDARY PLANT OPERATOP TO INVESTIGATE ISOLATED PHASE BUS DUCT COOLING SYSTEM.

DIiCUSSION:
o THE' RATE OF LOAD REDUCTION SHOULD BE BASED ON THE PATE OF RISE OF DUCT TEMPERATURE.
