The maximum allowed temperature for the insulation at the end of the fault (e.g., 160∘C160 raised to the composed with power cap C 250∘C250 raised to the composed with power cap C for XLPE/EPR).

Multiply the adiabatic current limit by the non-adiabatic correction factor to determine the final permissible short-circuit current. Applications in Power Systems Engineering iec 949 pdf work

: A factor is calculated to account for the heat that actually dissipates into adjacent materials. The maximum allowed temperature for the insulation at

The standard formalizes this with the famous adiabatic equation: [ k \cdot S = I \cdot \sqrtt ] Where ( S ) is the cross-sectional area, ( I ) is the short-circuit current, ( t ) is the disconnection time, and ( k ) is a factor derived from the material properties of the conductor and its insulation. The standard formalizes this with the famous adiabatic

He needed the specific factors for copper screening. He had the initial temperature ( 20∘C20 raised to the composed with power cap C ) and the final permissible limit ( 160∘C160 raised to the composed with power cap C ), but without the
