which is better ac or dc?

Answer Posted / linilbabu.ck

AC means alternating current of 230V/50Hz is long distance
transmision & It possible or heps of 50Hz signels applying
or carrying.AC supply causes power loss & its problems
solved with stepp-up transformer.DC means direct current DC
voltage power gain maximum(maximum current rating and
voltage rating) it doesn't long transmision. Nearest
transmision if DC voltage better than AC voltage.(need or
wated of powersupply)

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.
