Problem 1 A balanced three-phase star-coupled generator (R-Y-B phase sequence) is connected to a balanced three-phase star-connected load through a star-triangle (Y-A) transformer. The transformer has | V2 | = 230 V on the star side, and | V3 | = 115 V on the triangular side. The equivalent line diagram is shown in figure 1, the circuit diagram in figure 2 Figur 1 -100a Inles Figur 2 Task: On the generator side, a line-to-line voltage (ie VRY) of 23040 V is applied. Find it complex value of the current in the Y-phase on the primary side, if the current in the R-phase on the secondary side of load is 10040 A. Assume an ideal transformer.
