Power transformers - Part 5: Ability to withstand short circuit
Transformateurs de puissance - Partie 5: Tenue au court-circuit
|Standard number:||IEC 60076-5:2006|
|Language:||English/French - Bilingual|
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.
