Identifies the requirements for power transformers to sustain without damage the effects of overcurrents originated by external short circuits. Describes the calculation procedures used to demonstrate the thermal ability of a power transformer to withstand such overcurrents and both the special test and the theoretical evaluation method used to demonstrate the ability to withstand the relevant dynamic effects. Identifie les exigences pour les transformateurs de puissance pour resister sans dommage aux effets des surcharges occasionnees par des courts-circuits externes. Decrit les procedes de calcul utilises pour demontrer laptitude thermique dun transformateur de puissance a supporter de telles surcharges ainsi que lessai special et la methode de calcul utilisee pour demontrer son aptitude a resister aux effets mecaniques afferents.
