Chapter 2  Measurement Procedures

20

In the AC resistance range of IR4082, the earth resistance of the
ground electrode (D type earthing work) can be measured using
the simple measurement method (bipolar method).

2.6  

Earth Resistance Measurement 

(Function of IR4082)

What is the simple measurement method (bipolar method)?
The simple measurement method is a method used to obtain
the earth resistance by making use of the existing low earth
resistor as an auxiliary electrode when the additional earth
rod cannot be driven in, and is used in particular when check-
ing D type earthing work (evaluation standard 100 

).

Under this method, the sum of the earth resistances of the
test object and the earth resistor (Rx + Ro) is, in measure-
ment principle, the measurement value. Therefore, the earth
resistance of the existing earth resistor to be used must be
significantly lower than the earth resistance of the test object.
The neutral side of commercial power is normally laid with B
type earthing work (approx. tens of ohms or less) on the pole
transformer and so can be used in a simple measurement,
but the earth resistance can be high, so caution is necessary.

This measurement uses the neutral side of commercial
power. Before connecting, please use an electroscope to
confirm that it is the neutral side and be careful of electric
shock.
