Answer / sarav

We used Earth Megger for measuring the earth value.The
value of the earthing is vary depends upon the place.
In residential towers we should maintain the earth value is
below 2 ohm.

Answer / k. naresh reddy

We used Earth Megger for measuring the earth value.The
value of the earthing is vary depends upon the place. we
should maintain the earth value is
below 1ohm.(0.1 ohm is good earth resistance value)

Answer / rahul patil

EARTH RESISTANCE FOR GOOD EARTHING IS LESS THAN 5 OHM & GRID
RESISTANCE IS LESS THAN 1 OHM

Answer / kobina k. mensah

The earth resistance is checked using a earth resistance
tester and how good an earth depends on the type and number
spicks, voltage, soil and other facts.

Answer / mizan

below 1 ohm

Answer / dipeandra deepak

normly earth res.value for an industrial area is 1 to 5
res.for rock sail area and residential area, this value is
8 and 1-3 res respectively.further ithink this depends upon
ur mant. capability. this can be maintened by checking
earthing pit time to time. it also depends the size of
earthing patti and the load capicity set against it.

Answer / kallesh

By using Earth Megger to check the earth resistance and
Minimum earth resistances for good earthing is 0 ohm to 5 ohm.

Answer / anil

Now a days all telecommunication installations insist for value <0.5 ohms.
However domestic installation is ok upto 2 ohms.
The easiest way to measure the value of domestic earth is using a multimeter measure voltage across n-e it must be less than 5 ohms.

Answer / ashwin trikha

please give me the earth system

Answer / bhushan

value depends upon the soil resistivity but in reality it
should be zero to get better result. As per recommendation
by NFPA and IEEE it should be less then 5 ohms.

There is 3phase power cable from 1 point to the other point which is 100m away. Two point equipped with power meter and recorded 1st point is 205kW while the 2nd is 202kW and each phase average carry 400amps. To calculate the resistance of the 3phase power cable, is the formula using will be P=I2R?
