why we do 2 types of earthing on tranformer ie:body earthing
& nutral earthing , what is function.
i am going to instal a 5oo kva tranformer & 380 kva DG set
what should the earthing value

Answer / jayesh patel

Body earthing is used for body leakage current to earth &
not humen body harmful. Neutral earthing is used for
unbalance current pass through neutral & its goes to earth
& not effect on other phases voltages/load.

Answer / guest

The two types of earthing are Familiar as Equipment
earthing and Sysytem earthing.
In Equipment earthing: body ( non conducting part)of the
eqipment shold be earthed to safegaurd the human beings.

system Earthing : In this neutral of the supply source (
Transformer or Generator) should be grounded. With this,in
case of unbalanced loading neutral will not be shifted.so
that unbalanced voltages will not arise. We can protect the
equipment also. With size of the equipment( transformer or
alternator)and selection of relying system earthing will be
further classified into directly earthed,Impedance
earthing, resistive (NGRs) earthing

Both are equally importantand compulsory. As per your
requirement Earth pit value will be below 10 Ohms.

Answer / sarav

Ans 3 is mostly correct. But the value of the earthing is
below 2 Ohms.

Answer / riyadh

Star connection T/f's mid point of b/w two phase should be
neutral point . tat point is to be earthed ,
Body earth goes to ground the leakges in the T/f's to
protect human beings frm harmful

Answer / kunwar singh

Body Earthing : To ground any leakage current flowing in the e body of transformer & to protect human Body.

Neutral Earthing: To ground the unbalanced current in neutral.

The earth resistance should be below than 2 ohms.

Answer / 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.

Answer / pramod sharna

Basically earthing neutral earthing its protects fluctuation
of current and overloading and safety of equipment.

Body earthing is used to leakage of current.
