T&D UK are stockist distributors for Seba KMT LV, HV Power, & Telecom Cable Fault Location Equipment, along side Pipe & Cable Location equipment.
Seba KMT design and manufacture tools and equipment that assist in the diagnosis, fault locationand tracing of underground power, telecommunication and pipe networks.
Sheath testing and locating sheath faults is an essential process in maintaining all cable networks. Only externally intact cables guarantee long, fault-free operation.A damaged insulated cable sheath will inevitably result in a cable fault.
Cable Fault Location
1) Pre-location : determines distance of the position of fault
2) Pin-pointing : determines location of exact fault position in field

Cable Fault Locators, Surge Generators
Surge Generator Cable Fault Locators, ("Thumpers") provide pre-location and pinpoint cable fault location, cable thumping is very quick and limits expensive excavation by pinpoint accuracy.
Cable Thumping Explained
When a high voltage supply is applied to a cable fault, the resulting high-current arc makes a noise audible above ground. To achieve this requires a current in the order of tens of thousands of amps, at voltages as high as 25kV.The heating from this high current often causes some degradation of the cable insulation. If the cable fault engineer is proficient in the thumping method damage can be limited by reducing the power sent through the cable to the minimum required to conduct the test. Frequent testing can cause the cable insulation to degrade to an unacceptable condition.
Seba KMT Surge Generator Cable Fault Locators enable the detection of:
*Short Circuit Cable Faults
*Cable Cuts
*Resistive Cable Faults
*Intermittent Cable Faults
*Cable Sheath Faults
Many cable fault locating experts accept some insulation damage for two reasons:
1) when cable thumping time is minimal, so is the cable insulation damage;
2) there is no existing technology (or combination of technologies) that can entirely replace cable thumping.
