Rezumat
Studiul substatiilor electrice de tractiune in contextul actual este deosebit de important, prin specificul traficului feroviar,
care in ultima perioada a cunoscut o semnificativa reducere. Productia de marfuri industriale s-a diminuat mult in ultimi ani.
Transportul atat a marfurilor, cat si pentru calatori, a fost preluat in mare parte de tractiunea auto. Iata de ce puteri instalate in substatii de tractiune feroviare nu mai sunt utilizate in prezent la capacitatea proiectata. Este de inters analiza eficientei energetice la aceste instalatii, cu preponderenta studiul comportarii transformatoarelor de putere, in constructie speciala, care echipeaza aceste substatii don tractiunea feroviara.

Abstract
The electric substation traction study in present context is particular important in specific rail trafic, wich lately has seen a significant reduction. Production of industrial goods has declined over the past years.. Transport both cargo and for passengers was taken over bz the traction motor. That is whz installed capacitz in railwaz traction substation are not currentlz used to design
capacitz. It is interesting to analzye the energz efficiencz of these plants, mainlz studzng the behaviour of power transformers units, in special construction, which equips the electrical substation traction
