Do you know how to measure the earth resistance? if so explain it..

Answer / mahesh m

Earth resistance is measured by using earth Resistance
meter. it is using for four probe method.Two electrodes
for potentials and the other two for currents. There are
two methods, viz. Schlumberger method and Wenner method in
which two types of electrode assembly. There are special
formulae to calculate the resistance from the apparent
resistivity we get from the instrument. There are special
software to interpret the data.for current.

Do you know how to measure the earth resistance? if so explain it..

Answer / balaji

earth resistance is measured my earth megger instrument. it
has three terminals
1) earth
2) line
3) ground
in this ground is for meter protection and earth is meant for
point of starting of measurement , line is meant for point
until which the earth resistance to be measured
this works on principle that emf generated by the generator
is forms a close loop when the points between earth and line
conducts that is meter will indicate zero incase of the
failure of earth resistance

Answer / ankush shedge

Earth resistance is calculeted or measure by only Earth
Resistance Meter and that meter is prepared for specialy
earth resistance checking.Earth resistance must be less
than 1 Ohm if resistance increses Earth-Nutral voltage is
increses so maintain the earth nutral voltage resistance is
required less than one Ohm.

Answer / amit lukka

The answer written by By Mr.R. Sarkar & Mr. Dinesh R. are similar and correct, one thing is to be added that P2 and P3 are reference electrode and are placed 50 Ft. away from the pit and another reference will be 100 ft. from the pit and deep 1 meter.

Do you know how to measure the earth resistance? if so explain it..

Answer / rajshekhar jangnure

there are four terminals p1,c1,p2,c2 outof this earthing
electrode connected to p2 and p1 &p2 get shorted There are
three electrods which are 60 to 70 feet equal distant from
eachother along withearthing electrode whose earthresistant
tobecalculate .then set 10 oham range & connect all
electrodes as mentions above by 1.0sq mm wire & rotate the
handle with constant speed & note the
reading
