If DC supply is given to a transformer it may
a) Work
b)Not Work
c)Give lower voltage than the rated voltage on secondary
side.
d)burn the winding
Answer Posted / puja sinha
b)it will not work.because a transformer works on the
principle that an alternating flux is produced bya an
alternating quantity that oppose the main field.if the
supplied quantity is not alternating <alternating flux is
not produced and the transformer will not work.

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.
