12 Apr LKZ-700 – Routing of a cable with a broken conductor
Set the transmitter and receiver at the voltage mode (“E” or “U” marking) and connect it to the tested conductor. Other conductors in the cable and the other end of the broken conductor (when you have an access to the other end of the cable) must be grounded to prevent the penetration of electric field. The receiver will show the signal level as long as you move it over the cable route – up to the point of damage.
Due to the applied electric field (susceptible to damping), the method is not recommended for locating cables (depth too large = significant distance from the cable generating the field).
