Power Transformers Short Circuit Strength-Requirements and Test Code

This paper is a progress report presented by a Task Force, under the cognizance of the Performance Characteristics eristics Subcommittee of the IEEE Transformetee,s Commit- e, charged with the study and development of de- adequate definition of power transformer short circuit strength requirements and a test code for use in. the demonstration of such short circuit strength. A proposal for definition and a test code for demonstration of short circuit strength are presented together with discussion developed from suggestions from the IEEE Transformers Committee. As these items are further developed, they will be presented as proposed revisions to ANSI Standards C57.12.00 and C57.12.90.
