This adapter provides the ground tester with the unique capability to measure
individual ground resistances in multi-grounded systems using two clamp-on current
transformers.
The use of ground stakes is not necessary.
Before this method was available, users were required to disconnect an individual
ground path to be tested from other grounds to eliminate the influence of parallel
ground paths.
This was time consuming at the minimum and in many cases dangerous.
Once disconnected, the standard 3-pole/terminal ground testing method was used
which requires auxiliary earth stakes. In addition to consuming additional time, finding
suitable locations for the ground stakes can be difficult and in some cases, impossible.
The "stakeless" method of ground resistance testing eliminates these problems and
ideally complements the ground testers' standard testing methods.
