Underground Cable Fault Locator with TDR – Portable Power Cable Fault Tester for Open Circuit, Short Circuit, High Resistance & Flashover Fault Detection
Our Underground Cable Fault Locator with TDR is engineered for professional troubleshooting of buried and underground electrical cables.
The system combines digital waveform acquisition, TDR analysis and intelligent signal processing to help maintenance engineers quickly determine the distance to a suspected cable fault.
It is particularly suitable for situations where underground cables cannot be visually inspected and where traditional manual fault finding would require significant labor and excavation.
Some professional cable fault systems combine TDR with additional methods such as impulse current, multiple impulse and arc reflection for more complex high-resistance faults.
Ideal for:
Q: Can this tester locate a fault without excavating the entire cable route?
Yes. Fault distance measurement helps engineers narrow the suspected fault area before physical inspection.
Q: What is TDR?
TDR means Time Domain Reflectometry. It determines cable characteristics and fault distance by analyzing reflected electrical pulses.
Q: Can it locate high-resistance faults?
Depending on the system configuration, high-voltage flashover, impulse current, multiple impulse or arc-reflection methods can be used for high-resistance faults.
