Applications
•
•
•
Three-Point measurements of
resistance to ground of ground
rods and grids. Three-Point mea-
surements are generally used when
the electrode or grid can be easily
disconnected, if corrosion is
suspected, or in circumstances where
ground faults are unlikely to occur.
Four-Point tests or soil resistivity
measurements. Locating areas of
lowest soil resistivity is essential for
achieving an economical grounding
installation.
Touch potential measurements, an
alternative to 3-Point tests in
evaluating electrical safety. This
test is recommended when the
ground cannot be disconnected,
where ground faults are highly likely
to occur, or when the “footprint” of
grounded equipment (the outline of
the part of equipment in contact with
the earth) is comparable to the size
of the ground to be tested.
•
Two-Point tests for continuity
tests on bonding or on
pre-established grounds.
This test is commonly performed in
urban environments where proper
auxiliary electrode placement may be
obscured by confined real estate.
Measurements are referenced
against a good local grounded circuit.
