Cable Fault Location
HV & LV Cable Fault Location Services
Scotts Electrical Services provides specialist High Voltage (HV) and Low Voltage (LV) cable fault location services, helping clients identify and locate cable faults, minimise downtime and restore electrical systems safely and efficiently.
Our experienced engineers use specialist cable fault-finding and diagnostic equipment to locate faults within underground and buried cable systems. We support commercial, industrial, utility and infrastructure installations, from complex HV networks to LV distribution systems.
Our structured approach combines cable identification, testing, fault pre-location and precise pinpointing, helping identify the affected cable section while limiting unnecessary excavation and disruption.
Cable Fault Diagnosis and Testing
Our HV and LV cable fault location services can include:
- Open-circuit and short-circuit fault detection
- Earth fault location
- Cable identification and route tracing
- Underground cable identification
- Insulation resistance testing
- Continuity and conductor testing
- Time domain reflectometry (TDR)
- Fault pre-location
- Precise fault pinpointing
- Acoustic fault-location detection
- Magnetic signal-location detection
- Post-fault testing and verification
The appropriate testing methods are selected according to the cable system, fault type and site conditions.
Fault Pre-location & Precise Pinpointing
Cable faults can cause significant operational disruption, particularly when their exact location is unknown.
Our engineers first identify and test the affected cable before using specialist methods to establish the approximate fault position. Time domain reflectometry and other diagnostic techniques can be used during this pre-location stage.
Acoustic or magnetic detection methods can then be used where appropriate to pinpoint the fault more precisely. This focused approach helps reduce unnecessary excavation, disruption and the time required to access the damaged cable.
Repair, Testing & Safe Restoration
Once the cable fault has been accurately located, Scotts Electrical Services can provide full support with the required cable repair, jointing or replacement work.
Following the repair, we complete the appropriate circuit testing and verification before supporting the safe restoration of power to the client’s facility.
From a single damaged cable to a complex multi-cable installation, our team can provide a coordinated service from initial investigation and fault location through to repair, testing and return to service.
Need Help Locating a Cable Fault?
Our objective is to locate cable faults accurately, safely and efficiently, reducing unnecessary excavation and helping clients return their electrical systems to service as quickly as possible.
