HV Cable Commissioning Testing

Third-party, independent, high voltage cable testing, with a global fleet of RTS systems.

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.
