MRT-700 FF

Fault pinpointing on cables and pipes

The MRT-700 (*) device has the functionality of Fault pinpointing on cables and pipes. These faults are caused by the deterioration of the coating on the pipe and damage in the cable isolation, whereby the metal part of the cables and pipes may come into contact with the ground.

By combining the MRT-700 device with the A-frame connected to the receiver, it is possible to identify and locate the exact point of the faults. A special frequency – 8KFF – (Fault Locating Frequency) is injected to perform this detection work. High accuracy (<5 cm)

The MRT-700 allows simultaneous cable route tracing and fault pinpointing.

(*) MRT-700 device must be ordered with integrated Fault Detection Functionality.
