Is your cable monitoring strategy missing the bigger picture?
Partial discharge monitoring is a well-established technique — but it only tells part of the story. With insulation faults accounting for fewer than 25% of HV cable failures, and cable accessories responsible for 57% of all outage time, relying on PD alone leaves significant gaps in your asset health strategy.
This whitepaper by Dr Steven Blair cuts through the noise with a clear, evidence-based comparison of partial discharge monitoring and passive electrical and thermal sensing — helping you understand which approach is right for your assets, and why.
What’s inside:
- A plain-English breakdown of how PD monitoring (both online and offline) works, and where its limitations lie
- How passive optical sensing using distributed electrical sensing (DES) and point temperature sensing (PTS) monitors the failure modes that matter most
- Why joints and terminations — the most common failure points in HV cables — are better served by passive sensing
- A failure mode coverage comparison across both approaches
- Real-world visualisations and analytics from live Greenlight deployments
Who should read this:
This paper is essential reading for asset managers, network operators, and engineers responsible for the reliability and maintenance of HV cable systems — onshore or offshore.
