Hi,
We have GE 9001EA gas turbines, and we are suffering from intermittent 125 VDC ground.
The DC ground is existed as soon as the turbine get 40% of its speed (1200rpm)-exactly when the flame is appeared-, and stays in its situation. But the ground fault disappeared as soon as the flame is disappeared.
-What can the reason of this battery ground?
-Which devices that come into play at this phase?
NB: I verified the clutch coil of heavy fuel pump and the isolation was good.
Waiting for your help please.
