Direct connection with test leads – the most reliable method to trace individual cable or a pipe; Clamp (Included in the UAT-620 kit, optional for the UAT-610 kit) – provides an efficient and safe method of applying a locate signal to a cable, where it is not possible/safe to gain access to a cable for making an electrical contact
locating cable faults. Underground cables offers protection from weather conditions and pollutants, but it can be difficult to detect and repair faults. Unfortunately, traditional methods of identifying cable faults can be slow, expensive, and labour- intensive. This is where our project comes in: by using digital technology, we aim to ...
Basic cable fault locating methods. There are two basic methods of locating an underground cable fault. Sectionalizing This procedure, as shown in Fig. …
This paper proposes an accurate fault location method for underground power cable in power distribution systems. The cable is modelled using PSCAD EMTP simulation tool. The cable core as well as sheath and various grounding modes were considered in the cable modelling. The algorithm uses voltage and current measurements recorded at the …
Locating underground cable is necessary not only for finding faults, but also for undertaking any excavation possibly near a cable route. ... Before locating a fault in an underground cable, ... This method involves locating a specific line/cable by means of injecting specific frequency signal using a transmitter and the tracing it with a receiver.

Our cable fault locators are designed with a toolbox philosophy, incorporating advanced technologies that guarantee accurate and consistent results no matter the application. 3. …
Cable Fault Locator. Underground cable faults cannot be avoided due to many factors such as road widening, infrastructure improvement, digging carried out for repairs of other underground utilities etc. These faults generally take long time to detect and hence long time to repair the damaged cables and restore the power supply.
This would be the Arc Reflection method and can significantly reduce the thumping time necessary to locate the fault. It can be used to localize the fault and if necessary pinpointed using an acoustic fault detector. However, there are other underground electric power cable fault locating techniques you can try. One …

For shielded power cables, faults with a resistance higher than 200 ohms are almost impossible to distinguish from normal clutter reflections on the cable. Unfortunately almost all faults on primary underground distribution cable are high resistance faults in the area of thousands of ohms or even megohms.
