State Grid and China Southern Power Grid will invest a record RMB 825 billion in 2025, while Korea targets 100GW of renewables by 2030. Lifecycle insulation management is becoming Asia-Pacific’s common language.
What Is Partial Discharge? The Earliest Warning Sign of Insulation Failure
Partial discharge (PD) is the earliest measurable signal of insulation degradation in transformers, GIS, and power cables. Learn what PD is and the five trends reshaping PD detection in 2024–2026.
PD Detection FAQ: Online vs. Periodic, UHF-to-pC, and Big-Data Handling
Three of the most common questions about PD detection and online monitoring: how to choose between online and periodic testing, whether UHF readings convert to IEC 60270’s pC, and how cloud platforms handle the huge volume of PD data.
Heathrow Blackout: A Warning Ignored for Seven Years
The 2025 Heathrow blackout traced back to a transformer bushing fault flagged in 2018 oil tests. A case study in why PD monitoring data must translate into action.
Seven Oil Tests in Ten Days Couldn’t Stop It: Taipei’s Wanlong Substation Explosion
Before the 2021 Wanlong substation explosion blacked out 305,000 households, the transformer’s oil was tested seven times in ten days. Why DGA alone wasn’t enough — and where PD monitoring fits in.
A Substation Room Fire That Shook the Hsinchu Science Park
A 2022 fire in a gas supplier’s substation room caused voltage sags across Taiwan’s Hsinchu Science Park. Why large industrial users must monitor their own HV equipment insulation.
