Power transformers - Part 5: Ability to withstand short circuit IEC 60076-5:2006 ED3

Publication date:   Feb 7, 2006

Scope

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.
