Cable Fault Locators

A cable fault locator is used to pinpoint the exact location of a break, short or damage in an underground or concealed cable, helping teams target repairs without unnecessary excavation.

A cable locator traces the route of a cable. A cable fault locator goes further by identifying where along that route the fault or failure has occurred.

They can help locate open circuits, short circuits, insulation breakdowns and damage caused by impact, corrosion or ground movement.

Cable fault locators are commonly used on power, telecoms and site service cables. We can advise on suitability based on cable type and voltage level.

Accuracy depends on the equipment, cable type and ground conditions, but they’re designed to narrow faults down to a precise section of cable to reduce digging and repair time.

Basic training and electrical knowledge are recommended, especially when working with live or high-voltage systems. We can advise on safe operation and best practice.

Some methods require the cable to be isolated. We can advise on safe testing procedures based on your equipment and site rules.

Performance can vary with soil type, depth and moisture levels. We can help assess whether the equipment is suitable for your site.
