Total losses of a power transformer are subdivided in several distinctive parts. The I2R losses are easy to calculate and can be precise to a level of measurement repeatability and tolerances of the guaranteed material properties. The additional loss

Unaprjeđenje metoda određivanja dodatnih gubitaka u transformatoru može donijeti značajne uštede proizvođaču. Zbog toga je potrebno testirati potencijalne metode određivanja gubitaka na modelima. U referatu je dan prikaz istraživanja dodatni

Dodatni gubici bitan su čimbenik u projektiranju energetskih transformatora. Osim što želimo smanjiti ukupne gubitke, potrebno je i kontrolirati iznose gustoća gubitaka u metalnim konstrukcijskim dijelovima. Naime, velike vrijednosti gustoća gub

The subject of the analysis is a 300 MVA auto-connected power transformer in different loading conditions with regard to the load losses. During the electrical design time, some operating points of the transformer were analyzed in more detail using 2

U ovom radu obrađen je jedan od niza čimbenika u cjelokupnoj analizi problema otpornosti energetskih transformatora na kratki spoj kako bi se ilustrirala razina složenosti modela, odnosno detalja koja je potrebna pri analizi. Uspoređuju se analit

Different approaches can be used to calculate the magnetizing current waveforms in no-load conditions with or without DC bias currents flowing through the windings. One is to utilize the finite element method (FEM) as described in [3]. However, this
