Sir, my machine (Siemens gas turbine Model: SGT 700) is indicating an alarm "GAC in operation." as per OEM GAC stands for gas generator acceleration control. I am unable to identify the cause for this alarm to appear.

Please advise
 
Hi Nipendra,
Any finding on this?

What about the behavior of pilot/main Gas valve opening, IGV opening, load, shaft speed at the time of alarm? and any other alarm appears at the time of GAC in operation alarm?
