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 / 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 / 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.
