Detecting cables in
Detecting the pressure of cables, both in building walls or cavities and underground is a vital first step before works are carried out. Both detection only units and combined receiver transmitter styles are available.
The “cat and genny” combination provides the most flexible solution allowing signals to be injected directly or induced at a distance so the receiver can not only find a cable but also, with some units, give a depth indication TDR’s (time domain reflectometers) allow a measurement to be made of how far along a cable fault is formed.
These cable fault detectors require access to one end of the cable, although fault finding accuracy can be increased if both ends are accessible.
