If Vac1 208ej0 zero phase angle what is the voltage phasor

If V^ac_1 = 208e^j0 (zero phase angle), what is the voltage phasor of the corresponding secondary voltage V^ac_2? Assume ideal transformer operation. If V^ac_1 = 208e^J0 (zero phase angle), what is the voltage phasor of the secondary line voltage V^bc_2? Assume ideal transformer operation. Consider the above Y-delta transformer configuration with the secondary connected to a Y- connected balanced resistive load of R_L = 500 ohm. Using per-phase analysis and the real transformer approximate equivalent circuit model, with V^ac_1 = 208e^j0, find the following quantities. Commented Matlab code is acceptable. 3-phase load power 3-phase input active power Efficiency If a DC measurement of R_1 = 0.3 ohm, what DC resistance value would you expect to measure on the secondary terminals (R_2)? If the Y-load were unbalanced, with R_A = 400 ohm, RB = 500 ohm, and R_C = 600 ohm, what would the node O\' voltage phasor be (at the center of the Y-load)? What circuit quantity magnitudes would now be unequal? For this problem, assume that the primary side is excited with three-phase power with the standard relative phase shifts. The three three-phase transformers used in the circuit of Fig. 3 have the following properties. Primary turns: N_1 =100 Secondary turns: N_2, = 400 Mutual Inductance: L_m = 800mH Core loss resistance: R_e = 700 ohm Leakage Inductances: L_u +L\'_2l =1 mH Winding resistances: R_1+R\'_2, = 1 ohm Y-connected load: R_L = 500 ohm
