CONTRIBUTIONS TO ADAPT THE TRIVALENT ELEMENTS OF ALGEBRA TO THE GRAPHIC-ANALYTICAL METHOD FOR DETERMINING THE HOURLY INDEX OF A THREE-PHASE TRANSFORMER
Eng. Cristina PRODAN PhD, Assoc. Prof. Eng. Dorel CERNOMAZU PhD
Articolul evidentiaza o varianta grafica a metodei alimentarii in curentul continuu, aplicata in scopul identificarii indicelui orar al unui transformator trifazat, varianta care are la baza o constructie vectoriala. In final, sunt prezentate contributiile …

STUDY ABOUT THE DIAGRAM OF A TRANSFORMATIONS FOR A CLOCK-HOUR FIGURE OF THE VECTOR GROUP AT AN THREE-PHASE TRANSFORMER
Eng. Cristina PRODAN PhD, Prof. Eng. Adrian GRAUR PhD
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 circular…

VECTORIAL PROBABILISTIC MODEL FOR THE UNBALANCE
FACTOR OF A THREE-PHASE ELECTRICAL NETWORK
Lambert Pierrat (Franta)
In a three-phase power electrical network, the voltage asymmetry can be split into two different components. The first component results from the network structure and possesses almost constant value caused by asymmetry of circuit elements (e.g., lines, tra…
