Answer Posted / kanth
there is no need of earthing fo Dc systems
and in AC only earthing is needed
bcoz power generated from generators and ttransfer from
transformers ,so transrormers neutral's earthing has done
(in star-star or delta-star trafo)so phase currents goes
directly though earth or in neutral as a returned path to
transformer.
so we r using neutral for return path and earthing for
safety
