Mobile High Voltage Testing

In addition to our high voltage laboratory in Eastleigh, UK, we have extensive mobile high voltage testing facilities. High voltage tests are often required prior to returning a cable circuit into service following replacement of major components, such as cable joints or the diversion of an existing circuit. We can perform a full range of tests on a cable circuit whether as part of repair, diagnostics or routine maintenance performed in order to avoid a fault and hence a forced outage occurring in the future.In the UK, we have in-house, three HV resonance test trailers capable of testing up to 400kV. This means we have the capacity to mobilise multiple HV test teams at any one time, anywhere in the UK. Further capacity, when required, is available from our affiliates in Europe.  
 
We have a team of highly skilled operatives enabling us to offer a flexible service working with our customers to meet their installation programmes. We are also able to offer a wide range of ancillary testing services including PD monitoring, HV DC testing, sheath continuity testing and fault-finding services. 

Mobile Testing Facilities Include:

High Voltage Testing
• High voltage DC testing at voltages from10kV to 400kV. 
• High voltage AC testing at voltages up310kV. 
• Partial discharge monitoring on termination and joints while energisedby the AC test equipment. 
• Online partial discharge monitoring ofcircuits on load.

 

Low Voltage Testing and DC Testing
• DC conductor resistance tests. 
• Sheath resistance and continuity checks. 
• Contact resistance measurement. 
• Serving (oversheath) testing. 
• Oversheath fault location. 
• Insulation resistance measurement. 
• Cable sheath voltage limiter (tests for correct operation up to 15kV). 
• Cable cross bonding verification checks. 
• Impedance measurements. 
• Cable fault locations.
