Earth
Ground Loop Resistance Measurements for Commercial, Industrial and
Utility Applications
The
Fluke 1630 Clamp-on Earth Ground Tester simplifies ground
loop testing and enables non-intrusive leakage current measurement.
The compact and rugged design makes the Fluke 1630 easy to use in
small places and harsh environments, while the ‘display hold’ and
the continuity testing with an audible alarm function ensures
convenience in use. The novel technique means that earth ground loop
testing and continuity testing can be completed without breaking the
circuit.
Stakeless testing system
The Fluke 1630 uses the Stakeless testing method, which eliminates
the need to disconnect parallel ground rods and find suitable
locations for placing auxiliary ground stakes. This saves time and
enables users such as industrial and utility electricians, and field
service electricians and contractors, to perform earth ground loop
tests in locations where it is not possible to use other techniques,
including inside buildings or on power pylons. With the Stakeless
testing method, earth ground stakes are no longer necessary. The
Fluke 1630 Earth Ground Clamp is placed around the earth ground rod
or the connecting cable. A known voltage is induced by one half of
the clamp and the current is measured by the other half. The tester
automatically determines the ground loop resistance at this
grounding connection.

mA to 1000 mA, without needing to disconnect - ideal for system
troubleshooting
