Facing a challenge on a GE Frame 5 gas turbine. Lube oil header and differential pressure alarm and trip condition standing.
Filters have been replaced, oil lines have been flushed, oil completely drained and replaced with brand new oil. After all these the unit was started, it ran for 5 hrs and tripped again on lube oil header pressure low trip. At trip:
1.differential lube oil pressure was greater than 3.5bar and
2.differential hydraulic pressure was greater than 2.2 bar
3.control oil differential = 0 bar
Has anyone experienced this or any ideas on possible cause and solution on the problem?
