• On-Line Diagnostic PD Testing

    On-Line Partial Discharge (PD) testing provides an accurate assessment of the insulation condition for your plant rated at 3.3 kV and above. LIVE HV provides testing, while the plant is in service, with the HVPD Longshot and Kronos Spot Tester. PD testing can be conducted on CablesRotating Machines, Switchgear, and Transformers.

  • Cables

    LIVE HV can provide On-Line PD testing services for cables rated from 3.3 kV to 750 kV and use cable mapping to pinpoint any discharge detected to within 0.5% of the cables length. High Frequency Current Transformers (HFCT’s) are used to detect discharge from the entire cable length including any joints or terminations.

  • Motors And Generators

    On-Line PD testing is widely accepted as the best condition assessment tool for motors and generators rated from 6.6 kV to 30 kV. Testing can be made using portable or permanent High Frequency Current Transformers (HFCT’s) or permanently installed coupling capacitors.

  • Switchgear

    Our On-Line PD monitoring in switchgear can rapidly identify dangerous PD activity and diagnose insulation faults before they occur removing the chance for switchboard failure and increasing safety. Non-intrusive sensors including Transient Earth Voltage (TEV), Acoustic and High Frequency Current Transformers (HFCT’s) are used.
    If you are already taking PD measurements with a ‘handheld’ PD testing device LIVE HV can assist by providing diagnostic and PD location services.

  • Complete Network Monitoring – Hazardous Areas

    Using patented technology from HVPD, LIVE HV can provide complete network monitoring with HFCT sensors installed at the central switchboard. This was specifically designed for the Oil and Gas industry to enable PD measurements of HV motors installed in hazardous areas. The technique eliminates any requirement to install sensors at the machine, rather the sensors are installed in the remote switchboard.
