Time Domain Reflectometers (TDR)

Time Domain Reflectometers (TDRs) are designed to locate faults in metallic cables and wires. They work by transmitting an incident signal along the conductor and detecting any reflections.

About Time Domain Reflectometers (TDR)

Time Domain Reflectometers locate faults in metallic cables and conductors by transmitting an incident signal along their length and then listening for reflections of that signal. The strength, pattern and timing of the reflection will indicate where the fault is in relation to the TDR.

Time domain reflectometers (TDRs) are the principal means of detecting faults along extremely long metallic cables. They work by emitting an incident signal down the conductor and then listening out for reflections. A properly terminated cable with no faults will not produce any reflections so the TDR should detect nothing back.

A reflection, meanwhile, shows that there is a problem at some point along the cable and the TDR will assess the pattern, strength, and timing of the reflection to determine the fault's position and severity. TDRs are perfect for situations, where digging up a cable is impractical and constitute the least invasive way of testing for faults.
