Locating metal conductors

Test Instruments Africa (TIA) recently introduced a cable locator, Chauvin Arnoux’s CA6681, designed for the detection and location of faults in all metal conductors − electrical power cables, telecommunication cables and metal pipes.

Comprising a transmitter and a receiver, the CA6681 can be used on both current-carrying and non-current-carrying mains circuits. Its digital technology overcomes interference and disturbance signals to provide precise location details. The receiver displays the value of the signal measured, which is also shown on a bar chart or in the form of acoustic signals whose amplitudes vary in proportion to the signal distance. This allows for easy tracking of electrical cables through walls or the detection of buried pipes in gardens.

The receiver can quickly identify the circuit breaker or fuses corresponding to the socket to which the transmitter is connected, to guide the user and simplify the job. It can be used to detect short-circuits or cuts on existing installations. For example, it is possible to detect faults in under-floor heating pipes.


•        Location and tracking of lines and sockets.

•        Identification of the network voltage.

•        Identification of fuses.

•        Location of line interruptions.

•        Short-circuit detection.

•        Detection of the pinched or obstructed part in a non-metallic pipe.

•        Tracking of buried circuits.

•        Fault detection in under-floor heating systems.

•        Detection of metal heating ducts.

•        Detection of metal water pipes.

The cable locator is delivered complete with two units (transmitter and receiver) in a hard case with practical accessories for direct measurements on screw-in or bayonet lamp sockets or on mains power sockets.
