Analysis of temperature distribution in amorphous core dry-type cast-resin transformers via a finite element method

he amorphous core dry-type cast-resin transformer is a type of energy- saving transformer, which the no-load losses in the amorphous metal is generally lower from 60% to 70 % than regular electrical steel (silicon steel). In this paper, the iron core and winding thermal of the dry-type transformer are simulated/analysed via a finite element method. The analysis of temperature distribution characteristics of iron core and winding in transformers is a quite important problem for researchers to show the hot-spot and the temperature rise highest point. This helps manufacturers/designers to know a temperature distribution picture in the iron core and windings. Based on that, they can make in a suitable electrical insulation solution for the windings of transformer.
