For the security of the Turbine we have a special panel
called TSI ( Turbine supervisory instrument)panel. We
install more then 75 instrument (RTD , Thermocouple ,
Pressure switch, pressure Gauge, Pressure transmitter , and
most importantly we use VIBRATION PROBE , SPEED SENSOR , KEY
PHASER , DIFFERENTIAL EXPANSION PROBE, LVDT(for CASING
EXPANSION),Eccentricity probe ). And all these instruments
are terminated in this TSI panel.

If a control valve is hunting means means if we are giving 50% to the cv, the cv will open at 51% then slowly slwoly it will reaches 49% , so what to do for solve this problem. The cv is double acting and mounted for anti surge operation, it having 4 nos. volume booster, one sov, one positioner, etc..?
