Partial Discharge (PD) Monitoring Across the Asset Life Cycle
PD detection provides the best early warning indicator of electrical insulation deterioration in HV assets, 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 Cable Defects with 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.
- Time Domain Reflectometry fingerprinting to aid with fault location in the future.
Test Switchgear, Transformers and Cables 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 or precedence detection.
Monitor PD in Critical Assets with Continuous On-line PD Monitoring
- Provides immediate notification of concerning insulation degradation in critical HV assets on the network.
- Collates insulation condition for all monitored assets straight to user interface.
- Integrates with SCADA and cloud for remote access.
Prepare for On-line Spot Testing and Monitoring with Permanent Sensor Installation
- Facilitates 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.
