LV Cable Fault Location
Underground LV cable fault investigation, TDR pre-location, route tracing and repair coordination.
View service →Practical LV and HV cable fault investigation, TDR pre-location, route tracing, pinpointing and repair coordination — with specialist HV fault-location equipment brought in when the fault requires it.
We start with the fault, cable and network in front of us. Straightforward faults may be located with first-line testing and TDR. High-resistance HV faults may need specialist surge, ARM and acoustic equipment, which is arranged when required.

View service →Investigation following suspected cable strikes, damaged joints or abnormal cable performance.
View service →CableFaultLocation.co.uk works alongside R&D Cable Jointing, so suitable faults can move from investigation into cable repair without the client having to start again with a separate jointing contractor.
33kV work is reviewed against the cable system, circuit length, fault behaviour and specialist equipment required. Where a larger fault-location system is needed, the appropriate equipment is arranged for the job.
A simple process designed around getting useful information quickly.
Voltage, cable type, circuit length, protection operation and any test results.
Establish whether the fault is open, short, earth, low resistance or breakdown type.
TDR or specialist HV methods depending on the fault.
Trace the route and establish the excavation position where required.
Coordinate suitable cable repair through R&D Cable Jointing.
Cable faults rarely stop at finding a distance on a test instrument. The cable route needs to be established, the fault pinpointed, the correct cable identified and, ultimately, the damaged cable needs to be repaired.
With experienced cable jointers behind the fault-finding service, we can stay involved beyond locating the fault and help take the job through to repair and restoration.
Send us the voltage, site location and what you know so far. We’ll tell you what the next sensible step is.
