Sažetak

Distribution transformers, with their specific passive cooling mechanism, are investigated in this research. FEM
based approach was used for electromagnetic field distribution and losses calculation, following with the methodology for
thermal modelling. Detailed temperature measurements using thermocouples and thermal camera were done on 1600 kVA
unit, the results of which are compared against calculated values. The aim of this research is to present a viable approach for
adequate thermal modelling of distribution transformers applicable for research and design purposes.
