Time Domain Reflectometers - TDR

 

Time Domain Reflectometers (TDR) are a fast and easy method of measuring cables that have a minimum of two conductors separated by a dielectric. The basic operating principle of TDR is similar to that of RADAR, in which pulses are sent out into the cable where they experience reflections due to changes in impedance at faults (open and shorted), joints, areas of moisture ingress, connectors/taps, and corroded neutral wires, among others.

TDRs are great and easy tools to quickly determine the length of cable or locate short-circuits or low-resistive faults. TDRs can also be used in combination with HV thumpers to locate high-resistive or intermittent faults in all types of cables (Syscompact Series).
