Cable / Sheath Fault Locators & Thumpers
Cable locators are used for accurately identifying the presence of underground and overhead insulated line networks. They consist of receivers with signalling equipment and are suitable for use on high voltage systems.

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.
