【 摘 要 】

Taking two power transformers as examples, the core magnetic density in different winding short-circuit modesties calculated and analysed with finite element method software. The necessity of transformer short-circuit test required in the standard is explained. The software analysis model is set up based on different short-circuit test modes. Analysis results include the distribution of the core magnetic density and the value of the current in the winding. Finally, the analysis conclusion is given.
