Locating accessible buried cables
To locate a buried cable whose end is
accessible, connect one SG33 output to the
cable. If the cable has a grounded shield,
disconnect the shield from the cable end
SG33 is connected to and connect SG33 to
the shield. Ground the second SG33 output
in the opposite direction from the located
cable with a grounding rod, or to a nearby
grounded object.
Boost mode is recommended if the other
end of the cable has poor or no connection
to ground or the soil is dry. Buried cables
whose other end has poor or no connection
to ground have a section at the other end
that cannot be located. The length of this
section varies from a few meters to tens of
meters.
Conductive pipes and ducts can also be
located using this method.
