🌡️ IEEE C57.91 Aging (Arrhenius Thermal Insulation Life Acceleration Factor FAA)

Transformer Thermal Aging & Loss of Life Calculator

Calculate winding hottest-spot temperature ($HST ext{ in }^circ ext{C}$) and insulation Loss of Life acceleration factors ($F_{AA} = expleft[rac{15000}{383} - rac{15000}{HST + 273} ight]$) under IEEE C57.91: model cellulose paper insulation degradation during extreme overload events, predict remaining operational life, and power asset engineering yields.
