Equipment Used
: - Digital Earth Resistance Tester, KYORITSU- Model 4105A
Principle of Measurement
: - This instrument makes earth resistance measurement with fall-of-potential method, which is a method to obtain earth resistance value Rx by applying AC constant current I between the measurement object E (earth electrode) and C (current electrode), and finding out the potential difference V between E and P (potential electrode). Rx = V / I
Constant Current Generator
~ Voltmeter
V V=Rx x 1
E (Earth)
Procedure
P Potential
C (Current)
Rx = V / I
: - The auxiliary earth spikes P and C were sticked into the ground deeply. They have been aligned at an interval of 5-10 m from the Inspection point tested. The green wire was connected to the inspection point, the yellow wire to the auxiliary spike P and the red wire to the auxiliary earth spike C from terminals E, P and C of the t he instrument in order.
