Locating cable faults
Cable faults are sometimes difficult to
locate. It is possible that a failed cable has
multiple faults which may or may not be of
different types. Repairing some faults may
be necessary before the rest can be found.
Fault properties can change during locating
making work even more difficult.
Disconnect all conductors and shielding at
both ends of the faulty cable and use a
multimeter to determine the type of the
fault: short circuit, open circuit or a
combination of faults. If necessary, refer to
multimeter information for use.
Short circuit:
Connect SG33 between the
shorted conductors and leave other
conductors unconnected.
Open circuit:
Connect SG33 between
ground and the faulty conductor. Ground all
the other conductors and cable shield.
Boost mode is recommended.
