Power transformers - Part 5: Ability to withstand short-circuit

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.

Leistungstransformatoren - Teil 5: Kurzschlussfestigkeit

Transformateurs de puissance - Partie 5: Tenue au court-circuit

Identifie les exigences pour les transformateurs de puissance pour résister sans dommage aux effets des surcharges occasionnées par des courts-circuits externes. Décrit les procédés de calcul utilisés pour démontrer l'aptitude thermique d'un transformateur de puissance à supporter de telles surcharges ainsi que l'essai spécial et la méthode de calcul utilisée pour démontrer son aptitude à résister aux effets mécaniques afférents.
