In one of our 17.225 MW Alsthom Make Gas Turbine Generator (GTG), we are facing a slight problem with regard to the Hydraulic Ratchet Mechanism. The Jaw clutch is coming out/disengaging the clutch at the end of each Cycle. This is causing the limit switch 33 CSE1 to drop and thus restarting the cycle all over again.
We have checked the settings of all the check valves and relief valve and it is as prescribed. The self sequencer is also replaced but the problem persists. Pls advise.
