| Abstract: | This paper describes several failures of imported transformers in Guangdong,China,which were caused by low transformer mechanical strength,the resultant failure to withstand short-circuit current and the ensuing distortion of transformer windings.Defects in transformer design and manufacture are analyzed and some improving measures also presented,which is of referential value to the design,manufacture and type selection of transformers. |
