2 Fluke Corporation Fluke 1630 Earth Ground Clamp Meter
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, such as 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.
Applications
• Earth Ground loop testing in various installations
- for example, high voltage pylons, buildings, cell
phone substations, RF transmitters, etc.
• Inspection of lightning protection systems
• Leakage current measurement
