This factor accounts for heat dissipation into adjacent components like insulation, sheaths, or the surrounding soil. Determine Final Permissible Current (
Where:
In the transition to , the standard retained the adiabatic method for general use but provided guidance on calculating a factor for non-adiabatic effects (correction factors). These factors are relevant when the duration is long enough for heat to migrate into the insulation, allowing the cable to withstand slightly higher currents than the pure adiabatic formula suggests. iec 949 pdf work
