Is there any recommendation from GE regarding earthing & lightning protection for MarkVI system. Should the earth pit be separate from DCS & PLC. Should the value be less than 1 ohms.
Even though there is huge covering shed for the whole GT with separate earthing (for metal body), lightning is affecting cards in MarkVI panel.
