Smrekovina in macesnovina spadata med tiste vrste lesa, ki se pri nas v obliki masivnega lesa najpogosteje uporabljajo kot gradbeni, konstrukcijski in stavbni les. Za takšen namen uporabe je poleg mehanskih lastnosti lesa zelo pomembna tudi naravna

U radu su istražene metode za određivanje lokalnih gubitaka i zagrijanja metalnih konstrukcijskih dijelova transformatora. Tijekom istraživanja korištene su eksperimentalne i numeričke metode za određivanje iznosa gubitaka i zagrijanja na model

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

Transformer losses are important for designing the transformer. In this paper it is shown how tools based on finite element method (FEM) can improve the optimization process of a transformer. FEM tools help both in situations where something new or u

A special laboratory model for investigation of stray losses in transformer tank has been constructed. Stray losses represent the majority of measured total losses of the model what assures high measurement accuracy and certainty. Model consists of a

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
