Gas Turbine NO STATUS
Gas turbine went to NO STATUS during mode change over.

Our turbine is GE6FA and MARK V control system. we started load reduction due to non availability gas supply. At 19mw TTRF 1152c mode changed from piloted premix to lean lean mode. At the same time turbine went to NO Status. Again we take turbine into preselect and start the load reduction to our required load. why turbine went to NO Status during mode change over?

By "NO status" do you mean the STATUS field was empty, or that it displayed "NO Status" or "NO?

Yes Sir STATUS Field was become empty from PRESELECT load Selection.
