In frame 6B machine, Some times Sudden Temperature drop of 25 to 30 Deg C observed in Atomising Air Temp. and at the same time AA pressure starts hunting and condensate also observed from AA1 drain. GT was running on Gas Fuel at that time. It remains with same condition for 2 to 3 days or more and after that all three parameters get normal on its own. The same phenomenon has been observed 3 to 4 times in past. No alarm appears in mark during this action.
Pl. help in analysis.
(As per my knowledge, main problem is AA compressor discharge pressure hunting which in turn is causing AA temperature drop resulting in condensate from AA1 drain.)
