Windings and clamping structures must withstand the peak radial and axial forces without permanent deformation.
IEC 60076-5 is the international standard that defines the requirements for power transformers to withstand the physical and thermal stresses caused by external short circuits. It is part of the larger IEC 60076 series and applies to both oil-immersed and dry-type transformers. iTeh Standards Core Objectives iec 60076-5
Establishing the duration of the fault the transformer must withstand. Windings and clamping structures must withstand the peak
: The mechanical strength required to resist the physical forces (stresses) that occur during a short circuit. iTeh Standards Key Technical Aspects Transformer Categories iec 60076-5
