Measurement of the earth electrode resistance
(3-Pole method)
[MODEL 4102A/KEW 4105A]
The international standard IEC 60364-6 provides information regarding the measurement of the resistance of an
earth electrode for TT, TN and IT systems.
This measurement shall be made by the Volt-Amperometric
method using two auxiliary earth electrodes.
The instrument that covers this requirement is the Earth
Tester.
