Answer Posted / nitin naik
1)Body Earting:- It is a part of earthing process were we
are connecting the metallic part of the equipment to the
general mass of the earth (earth is a zero potential) to
ensure any leakage current due to failure of the insulation
of the active conductor. If it is not ensured & suppose
there is leakage current it may cause electrical shock to
the person touching the metallic part of the equipment.
2) Neutral Earting:- It is being ensured & essential where
we are installing distribution transformer (Delta to star)
& Three phase neutral DG set, Neutral earting is the
process of earthing the star point of the secondary winding
of transformer & star point of the alternator winding to
the general mass of the earth. It is essential to eliminate
the return current in neutral due to unbalanced voltage &
further to eliminate unbalance potential between the
circuits.
Note:- In both the case earth setups resistance should
below 2 Ohms.

in cvt,there are two windings,1a,1n and 2a,2n.in my one project i use only one winding i.e.1a,1n. the other winding is not in use, so i connect it in open delta and want to close it by ibsertibg thermal resistor. the output of cvt is 132kv/115/sqrt3. plesae tell me exact value of resistor, so i may close it to avoid the resonance phenomenin. send me answer on this email adress please. aetcon-po@aetcon.com
