Abstract
The complex considerations associated with the design and demonstration of short-circuit withstand capability in power transformers are discussed. A model testing technique is described as a means of defining failure modes and failure stresses. One failure mode involving buckling of a winding subjected to inward radial forces is analyzed on a dynamic basis. Alternative means of capability demonstration are proposed and additional experience with the recurrent surge generator method of failure detection is presented.Keywords
