Annotation of standard text IEC 60949-ed.1.0 :
The approach set out in this standard is to: a) calculate the adiabatic short-circuit current, b) calculate a modifying factor that takes account of the non-adiabatic heating effect, c) multiply a) and b) to obtain permissible short-circuit current. Lapproche presentee dans la presente norme consiste a: a) calculer le courant de court-circuit adiabatique, b) calculer un facteur de correction qui tient compte de lechauffement non adiabatique, c) multiplier a) par b) pour obtenir le courant de court-circuit admissible.
