5762N High
Resistance Fault Locator.
The 5762N Resistance Fault Locator is a portable
cable fault locator for determining the position of a single
shorting fault between two conductors, or between one conductor and
the cable sheath or ground.
The fault locator can be powered from a mains electricity supply or
from the internal battery that is automatically recharged when the
instrument is connected to the mains.

A high
input-resistance differential amplifier
circuit is used to drive the detector allowing
faults of up to 200MΩ to be accurately located.
A maximum potential of 6V (limited to 1A,
or 10A
if 10A BOOST button is held) is applied
across the bridge circuit and therefore the cable
under test.
The 5762N High Resistance Fault Locator
is housed in a rugged highly luminous
case manufactured from a high impact copolymer
and featuring an
internal metal sub-frame
for added strength.
When closed, the case is
rated to IP67.

The 5762N High
Resistance Fault Locator is equally suitable for use in the factory, to find faults
in stock cable, or in the field to locate faults in an installed
system. The fault is located by manually adjusting a potentiometer
to find the null point as indicated on a front panel meter. The
instrument uses a bridge circuit with the two sections of the faulty
conductor (either side of the fault) acting as one half of the
bridge network and the internal pushbutton potentiometer forming the
other. The potentiometer is adjusted until the null is found, at
which point the distance to fault can be read from the instrument as
a percentage of cable length.
