I would like add a point to reena:
Generally we choose transformers with same capacity and impedance for redudandancy in Process plants to avoid power interruption to process.. and we do paralleling of trfs to carryout load shiftings without interruption especially critical loads.. (this is not in the case of lighting etc. where interruption really doesn't matter.)

In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.
