HV Cable Fault Finding
HV Cable Fault Finding
HV Cable Fault Finding – Cable deterioration occurs naturally with age, especially when exposed to elevated temperature due to high loading and even when it is not physically damaged. Many substances such as water, oil and chemicals can contaminate and shorten the life of insulation and cause serious problems. C&P carry out fault identification services either above or below ground to locate the cable fault and repair as soon as possible.
Typical cable faults can occur as either earthing or open circuits and can also be permanent or intermittent. High Voltage Services use the latest fault location instruments and equipment and are able to assess and identify cable faults such as earth faults, cable damage, resistive faults, phase to phase faults, intermittent faults, partial discharges and sheath faults.
All of our HV electrical personnel are fully trained and we provide both HV and LV cable fault finding and repair services to the highest possible standard.
We provide full HV electrical testing services for HV pressure testing up to 68kV and sheath and cable fault identification. We have the test capability to identify and locate cable faults for systems up to 33kV.
