Cable fault location
Fault location is the process of identifying where a cable has failed (or is likely to fail), so repairs can be planned safely and efficiently.
What the service is
Cable faults can present as trips, insulation breakdown, sheath issues, or intermittent events. Fault location work varies with cable type, voltage level, installation method, and what access is available.
Who typically needs it
- Operators with MV/HV networks (utilities, industrial sites, campuses)
- Contractors managing an outage where route excavation needs to be targeted
- Sites with repeated trips or suspected insulation deterioration
What a typical engagement includes
- Confirming the faulted circuit and isolations (per site rules)
- Testing and diagnostics appropriate to the asset and failure mode
- Providing an estimated fault location and a confidence level
- Support during excavation/repair and post-repair testing (scope dependent)
What to provide for a quote
- Cable details (type, approximate length, voltage level, termination points)
- Route information (drawings, duct routes, joint bays, previous repairs)
- Event history (what happened, protection indications, any test history)
- Access constraints and outage window
