Summary
Investigation of a dry-type transformer fire on Åsgard B examines probable winding-insulation degradation leading to a short circuit or arc flash. It reviews protective instrumentation, maintenance limitations, transformer working-life arrangements and shortcomings in applying earlier incident learning. Firefighting, water cooling, thermographic checks and partial evacuation are documented; nobody was injured.
