and visual judgment. It is a device that completes the precise
positioning of the cable fault point within the rough measurement
range and collects the acoustic and magnetic time difference. It
integrates positioning technology, path-assisted testing and other
technologies, providing multiple test modes and rich and diverse
prompt information to efficiently and accurately complete cable
fault location.

3. Cable route tracer(Cable fault comprehensive tester) (XHGX507)DescriptionXHGX507 underground cable pipe locator is mainly used for cable
fault location, cable identification, cable path and depth
measurement. It can complete tasks that could only be accomplished
by a few sets of instruments in the past.Working principleThe underground cable pipe locator is designed based on the
electromagnetic induction method and the application of the
communication principle.1.The electromagnetic signal is generated by the transmitter, and
the signal is transmitted to the underground cable under test
through different transmission connection methods.2.After the underground cable induces the electromagnetic signal,
an induced current is generated on the cable, and the induced
current propagates along the cable to the distance.3.In the process of current propagation, electromagnetic waves are
radiated to the ground through the underground cable. When the
receiver detects on the ground, the electromagnetic wave signal
will be received on the ground above the cable.4. The position, direction and fault of the underground cable can
be judged by the change of the received signal strength.
FeaturesThe large-screen LCD displays the signal strength, and the bar,
arrows and voice prompts make it easy for the operator to judge the
underground position of the cable and the fault point. One person
can do it all.All-digital design, clear large-screen LCD graphic display and
