About Cable Fault Locators

A cable fault location is required anywhere when the fault cannot be seen. The faults are typically damaged cables that affect the resistance in the cable. If allowed to persist, this can lead to a voltage breakdown. A multi-step process must be performed as safely and as quickly as possible to prevent customers from going without power.

In this category, we have an array of cable fault-locating instruments. Megger, EA Technology & BAUR offer the broadest selection of tools on this page. However, many other high-profile companies offer incredible alternatives enriching the scope of products available in this section.

Please utilise the Manufacturer and Price filter options to help you locate the instrument to suit your needs.
