Rezumat
Lucrarea de fata isi propune sa realizeze o comparatie intre transformatorul obisnuit si un tip de transformator special reprezentat de transformatorul cu infasurari deplasabile, la care una din infasurari este o bobina mobila conectata in scurtcircuit iar infasurarea primara este divizata in doua semibobine identice concentrice cu bobina mobila. Studiul comparativ vizeaza partea de scheme echivalente a acestor doua dispozitive si prezinta diferentele intre cele doua tipuri de transformatoare.

Abstract
This paper aims to realize a comparison between the usual electrical transformer and a special device represented here
by the transformer with mobile winding, at which one of the windings is divided into two identical coils that are concentric with an third coil that is mobile and connected in short circuited. The comparative analyses aims to present the equivalent scheme of this
two voltage regulation devices and shows the main differences between this two types of transformers
