non-adiabatic heating effects

Unlike simpler methods that assume no heat escapes the conductor (adiabatic), this standard provides a method to account for , meaning it considers heat transfer to surrounding materials like insulation or armor. Core Calculation Principle IEC 60949 (often referred to as IEC 949)
