Articolul evidentiaza ca trecerea de la un indice orar la altul se realizeaza prin parcurgerea diagramei
transformarilor fie in sens trigonometric, fie in sens invers trigonometric. Parcurgerea diagramei trasnformarilor se poate face prin permutarea circulara a liniilor sau coloanelor in sens direct sau invers, ceea ce echivaleaza cu modificarea
legaturilor din N in Z sau din Z in N, la bornele infasurarii primare sau secundare, modificari care se efectueaza de cate ori este nevoie, in functie de indicele orar la care se ajunge.

Abstract
Article shows that the transition from one clock hour figure of the vector group to another, is achieved by
following the transformations diagram, be in the clockwise, or counterclockwise. Crossing through the transformations diagram, can be made by the circular permutation of the lines or of the columns, in direct sense or in inverse sense, which is equivalent to changing linkages from N in Z or from Z in N, from the primary winding terminals or to the secondary
winding terminals, changes which are made whenever needed, depending on the clock hour figure which is reached.
