Answer / rr0505
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 / rvg.msceb
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.

Answer / shri6181
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

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

Answer / rakesh
For grid resitance it should be less than 5 ohms and for
indipendent earth pit it should less than 2 ohms.

Answer / kalpesh
earthing resetens 1 ohm to 3 ohm in rainy sesion only 1 ohm &other sesion aprox 3 ohm
| Is This Answer Correct ? | 9 Yes | 3 No |
Answer / kalpesh
Earth pit resistance 1.4 TO 1.6 NORMAL CNDITION
| Is This Answer Correct ? | 11 Yes | 6 No |
Answer / nandakumar.r
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.
