High Voltage (HV) Cable Commissioning and Maintenance Optimization
Kinectrics
is uniquely qualified to perform Hi-Pot qualification and “proof of function”
cable tests on high voltage (HV) power cables and offers cable testing
services using an advanced high power Mobile Resonant Power Supply system rated
260 kV at 83 amps for transmission class cable lines.
Kinectrics’
cable commissioning testing services encompass cables with extruded insulation
and high-pressure fluid-filled (HPFF) cables as well as the associated
accessories.
On-Site
HV Cable Commissioning Testing with Kinectrics Mobile Resonant Test System (RTS)
Kinectrics’
variable frequency Resonant Test Sets are capable of performing
post-installation tests on transmission class XLPE cables. Kinectrics has
tested more than 6,500 km of HV cable rated 66 kV and above.
The
Kinectrics RTS is also equipped with state-of-the-art broadband partial
discharge detection equipment to help identify incipient insulation flaws.
Broadband partial discharge technology can help identify insulation issues that
may not cause failure during an AC Hi-Pot test.
The
Kinectrics RTS has performed successful AC Hi-Pot and partial discharge cable
commissioning testing throughout North America, the Caribbean, Europe and
Middle East.
We have
successfully tested one of the longest cable systems of over 51 km with 47
accessories using 4 RTS units in a master-slave parallel configuration.
Partial Discharge Testing (PD)
Partial
Discharge (PD) testing is a predictive, diagnostic test used to identify
problems (defects within cable terminations and joints / splices). PD
testing is performed on-line, either in service during a Soak Test, or off-line
during an AC Hi-Pot test.
Early detection of partial
discharges helps utilities avoid costly high-energy cable failures, which may
result in the need for cable repair or replacement, lost power generation
revenue and subsequent grid complications.
