Hi guys,
M new here,
currently I am working with GE supplied Gas Turbine Frame 6 machine. Recently we had shutdown for one of the gas turbine, and after 3 hours of rachting <i>[moderators note: I think he means ratcheting]</i> "Rachet trouble" alarm appeared. And on machine racthing was not happening.
We checked starting clutch solenoid valve 20CS-1, and found one of its drain port choked with foreign materials.
Lastly we found 20CS-1 SOV -ve supply fuse blowned off.
I want to know the cause of "Rachet trouble" alarm. Did fuse blowing caused the ratching to stop???
Does 20CS-1 need to be remain energised for ratching??
