Alstom typhoon Gas Turbine Tripped on "Off skid gas fuel vent valve failed open" fault. After 15 minutes of tripping, the fault was gone and turbine was on ready to run prompt. This happened thrice in 6 months. I want to know whats causing this problem because its quite confusing and like chasing a ghost. Apparently there is no problem but the fault caused three trippings and then went away.
