11kV faults can range from straightforward low-resistance failures visible on a TDR to high-resistance breakdown faults requiring surge, ARM and acoustic/electromagnetic pinpointing. We scope the fault first and arrange the appropriate equipment for the cable and fault type.
What the service can include
- Initial fault classification
- TDR pre-location
- Specialist ARM / surge pre-location where required
- Cable route tracing
- Acoustic/electromagnetic pinpointing where required
- 11kV cable repair through R&D Cable Jointing
What we need from you
Send the site location, network voltage, approximate cable length and type if known, what protection operated, any existing IR/continuity test results and whether the cable route is known. Photos of terminations, switchgear labels, drawings or previous test records are useful where available.
Repair after location
Where a fault position is confirmed and the cable is safely isolated and accessible, suitable repair works can be coordinated through R&D Cable Jointing .
