Offshore Wind at 72.5 kV: Why DC Control Power Now Sets Availability and O&M Cost
Offshore wind reliability is often discussed in terms of primary equipment strength: main transformers, GIS, circuit breakers, instrument transformers. That focus made sense in the 35 kV era. But as offshore turbines move toward 72.5 kV tower-base transformer/GIS bays , a different constraint is becoming decisive: Availability is increasingly determined by the DC control power chain that feeds protection, control, communications, and switching circuits—specifically whet
