Field Applications
This ground resistance clamp meter is designed to test the ground
resistance of any loop system. In addition to measuring the ground
resistance of electric power transportation conductors and
communication circuitry, this meter also measures the ground resistance
of electric equipment and lightning arresters. When the current in
the grounding loop has been disturbed, the resistance measurement
can be affected. The interference current can be tested by the ground
resistance clamp.
Principles of Measurement
Rx:
Ground resistance value to be tested
R1//R2//…Rn:
multiple parallel ground resistance
Rearth:
normally 0Ω
Rguard wire:
normally 0Ω
Rloop=Rx+(R1//R2//…Rn)+Rguard wire
When R1//R2//…Rn<<Rx, then Rloop=Rx
