For DG or Transformer body earthing, is it necessary to terminate the earth bus to earth pit directl..

Answer / ravi nayak

May be the answer i guess is if not terminated directly to earth pit, in abnormal cases the leakage current will find 2 paths to flow one will be to earth pit and other will be to any other structure/equipment connected to common strip because not terminating in earth pit ensures to form a junction with common earth bus. And hence tending to provide 2 pathways for discharging itself.
