I completely agree with Rvg. SMPS is the best possible
solution when it comes to varying the frequency and
voltage. Good thinking Rvg. Compact, efficient and
effective, the only disadvantage is radio noise created by
it which can be easily shielded.

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.
