Question
1. how much normal earth resistance in earth pits(neutral 
and body earth) and transformer neutral and body earth & 
panel earth.
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Earth resistance of earth pits shall depend on the terrain
in which the same is provided. Accordingly, based on soil
resistivity data of the location, no. of earth pits is
determined to ensure Grid earth resistance value below 5
Ohms for electrical grids,

For solidly grounded neutral of transformers, resistance
between Neutral & Body earth as well as panel earth shall
be zero.

Answer
# 2
The earthing resistance indicates the easiness of providing
a path. It should be as low as possible. Different
countries having standard values. In india, for commertial
applications its <1 ohm, and for railway its< 0.5 ohm.
for air craft and ships temp. earthing <10 ohm.etc.

NUETRAL&EARTH BETWEEN VALUE IS 0. AND TRANSFORMER BODY
EARTH AND NUETRAL BELOW 1OHM,ANDRESPECTIVELY PANEL EARTH
ISALSO BEBELOW 1OHM.

Answer
# 4
even any earth pit is concidered every earth pit should have the value 0ohms.but in rare cases u will get that value,more over will come 0.3to 0.9,there fore the earth pit value should be less than 1 ohm.ok 
Is This Answer Correct ?    32 Yes 4 No

Answer
# 5
For grid resitance it should be less than 5 ohms and for
indipendent earth pit it should less than 2 ohms.
 
Is This Answer Correct ?    39 Yes 27 No

Answer
# 6
Earth pits resistance was 0 ohms.due to soil difference its
vary slightly near 2 ~ 3 ohms.But its acceptable level in
our country.

For transformer neutral and body earth and panel resisteance
was zero ohms.

What are the role of each components in PID COntroller BARC 1
We have 2 Nos. Transformer with the capacity of 2000KVA and 1250 KVA and currently using only one 2000KVA T/R during operational hours while non- operational hous 1250 KVA T/R also used to reduce T & D losses. Similarly, 2 capacitor bank of 500KVAR and 300 KVAR also installed to balance reactive power. Now problem is around 1000 KW load PF is not maintaning 0.99 as 350 KVAR capacitor is in healty condtion. Now the PF is maintain 0.95 to 0.96.   2
