Partial Discharge Monitoring Across the Asset Life Cycle

Partial Discharge (PD) detection provides the best early warning indicator of electrical insulation deterioration in HV assets operating above 3 kV, both onshore and offshore including switchgear, transformers, cable terminations, land and subsea cables. Whether implemented at project start-up or during the asset’s lifespan, we support critical networks to reduce the consequence of failure.



Detect Inter-Array Cables defects during commissioning and after Repair with Diagnostic VLF Testing

  • Testing during commissioning, maintenance and after repair to ensure installation integrity.
  • Monitored withstand tests with PD for insulation defects and Tan Delta for water ingress.
  • TDR fingerprinting to aid with fault location in the future.
  • Read more about our Test Services for cables.





Test Switchgear, Cables and Transformers whilst In-service with On-line PD Spot Testing

  • Detect the early stages of insulation deterioration with routine spot testing throughout the export and inter-array network.
  • Pinpoint and locate any issues with PD mapping.
  • Read more about our Test Services for switchgear, cables and transformers.



Monitor PD in Critical Assets with Continuous On-line PD Monitoring

  • Immediate notification of concerning insulation degradation in critical HV assets on the network.
  • User interface collates insulation condition for all monitored assets.
  • Cloud integration, SCADA interface and remotely accessible.
  • Read more about our On-line PD Monitoring System.





Prepare for On-line PD Spot Testing and Monitoring with Permanent PD Sensor Installation

  • Sensors installed to facilitate On-line PD spot testing and monitoring of the export inter-array network at substations and wind turbines.
  • Avoids the need for outages to temporarily attach and remove PD sensors for the purpose of conducting On-line PD spot test measurements.
  • Read more about PD sensors.
