HV Jointing & Termination

more info

V-TES specialise in cable Jointing and Terminations from LV up to and including 132kV on all types of cables.

Whether a straight splice or a motor termination, it’s essential that cable jointers are trained, competent, and familiar with your equipment.

Our fully Nexan qualified engineers have the equipment, certificates, and experience to carry out any job to the highest of standards.

Partial discharge image

High Voltage Partial Discharge

more info

Partial discharges (PD) are localized electrical discharges which only partially bridge the insulation between conductors and which can occur adjacent to a conductor.

PD occurs on high-voltage lines, in windings and other electrical equipment. PD can occur due to faults in windings caused by faulty enamelled wires, air pockets during casting, insulation faults or similar. Testing and analysis can be performed on both rotating equipment and switchboards

TDR & OTDR Cable testing & analysing

more info

V-TES offer (TDR) Time Domain Reflectometers - this is used for accurate cable fault detection and pre-location on HV/LV metallic & fibre optic cabling systems for Oil & Gas, wind farms, Telecommunications and on any cable network in any location. This form of cable testing is executed by transmitting an incident signal on to the cable and listening for the signal reflections.

Thermal Imaging Zone 1 & Safe Area

more info

Thermographic inspection surveys can be used as a tool for the early detection of problems across a wide range of industries and applications.

Regular inspection and analysis of IR data allows remedial actions to be taken before system failure.

Non-intrusive thermal surveys identify electrical faults and hot spots in switchboards and control panels such as overloaded circuits, faulty switchgear, and loose terminations.
