How we do it
Cable fault location
01
Test
The insulation is tested with high voltage and the fault type is identified.
02
Distance
A pulse travels along the cable and reflects from the fault; the return time gives the distance (SPC20, synchronous mode).
03
Pinpoint
The PP20 pin-pointer locates the exact spot on the surface using acoustic and magnetic synchronisation.
04
Report
The fault location and test result are documented in a report.
FAQ
FAQ
How do you find a fault without digging?
We measure the distance with reflectometry, then pinpoint the spot with the PP20 using acoustic and magnetic signals.
Can you find weak faults?
Yes, the SPC20 keeps a stable arc at the fault and finds weak and intermittent faults.
Does the mobile lab come to site?
Yes, the equipment is brought to your site by vehicle.
Do I get a document after the cable test?
Yes, a signed test report.
