Rezumat
Pornind de la defectarile transformatoarelor electrice de putere, observate pe parcursul exploatarii acestora, am abordat aceata problema pe baza unor simulari efectuate pe calculator. Analiza defectelor la un transformator de putere cu ajutorul programului Flux 2D este o metoda organizata si creativa ce are ca scop cresterea sigurantei in exploatare a acestor echipamente electrice. Sunt prezentate fazele si iteratiile, care combina experienta din exploatare cu viteza de calcul a computerului si rezultatele grafice obtinute in Flux 2D.

Abstract
Starting from the failures of power transformers, observed during their operation, we approached this problem
based on computer simulations. A failure analysis to a power transformer with program Flux 9.3.1 is an organize and creative method at increasing the operational safety of the electrical equipment. Phases and iterations are presented, which combines operational experience with the computing speed of the computer and the results graphics obtained in Flux 9.3.1.
