heal.abstract	Transformer thermal performance is a critical issue during the design stage, since it indicates its ability to operate reliably through its lifetime and under possible overloading conditions. This paper introduces a hybrid thermal modeling technique that links numerical methods to analytical calculations, providing a tool for accurate prediction of temperature distribution characteristics in the expense of relatively reduced computation time, enhancing transformer design calculations often based on empirical methods. © 2006 IEEE.	en
