, formally titled "Calculation of thermally permissible short-circuit currents, taking into account the non-adiabatic heating effect," * fills a crucial gap. It provides a method to determine how much short-circuit current a conductor can withstand without assuming that all heat remains inside the conductor (the adiabatic assumption). This is especially important for short durations and small conductor cross-sections.
