"Temperature class 40," Elias muttered, swiping through the PDF. He was looking at the service conditions section. He knew that if these transformers weren't built to the exact specifications of the standard, the internal insulation would degrade. A single failure here would trigger a cascade, plunging the entire valley into darkness during the worst possible time. A single failure here would trigger a cascade,
