Cable fault locating

If left undiscovered, faults on underground cables can lead to a voltage breakdown, which can cause unnecessary and costly downtime for your plant or equipment.

Electek’s cable fault location service has been designed with two purposes in mind: to detect any potential faults that may cause a problem in the future and to locate and repair any faults that may already be causing problems.

Using state-of-the-art equipment, our highly-trained experts handle every stage of the process, from location of the fault and daylighting, to testing, splicing and restoration, quickly and efficiently getting your facility operational again.

State-of-the-Art Equipment

Our testing methods and equipment

With our state-of-the-art TDR and thumper equipment, Electek are the fastest solution to get your plant or equipment back online when you discover a fault.

Using an arc reflection filter, we are able to combine both traditional fault location methods pulse reflect and transient to find faults in less time and with a significantly reduced risk of damaging the good cable.

Our use of an arc reflection filter allows us to connect both a time-domain reflector (TDR) and surge generator to a faulted cable. The TDR can then monitor the cable and measure the distance to a fault while the surge generator sends polarised waves out from the fault. Not only does this reduce damage to the good cable, but it also provides a prelocation measurement that is almost always within a few metres of the fault.

Once we’ve quickly deduced the approximate location of the fault, we can carefully pinpoint the fault before daylighting, repairing, testing and restoring the cable – getting your plant or facility up and running again as soon as possible.
