Hi,
9E GE Gas Turbine with MK6e, For about 2 month we suffered with a ground fault. it's appears only after opening the generator breaker, taking about 3 to 6 minutes and disappears again.
3 or 4 times the alarm persists until we come. We suspected at first time 33CB-4. after we remove its cable the alarm disappeared, but it doesn't reappear when we return the cable to its place (that happened for 3 times about).
We changed its cable (33CB-4), but the problem is the same.
-Can the Discret IO Card be the original of this problem?
-Is there an explication for the phenomena of disappearing/Not reappearing of the alarm while decabling/cabling the suspected instrument?
Thanks for all your contributions
Regards
