3 The phase voltage at the terminals of a bal- anced three-phase Y-connected load is 2400 V. The load has an impedance of 16 + j12 02/ and is fed from a line having an impedance of 0.10j0.80 2/d. The Y-connected source at the sending end of the line has a phase Note that the phase sequence is acb. A sequence of acb and an internal impedance of 0.02j0.16 2/6. Use the a-phase voltage at the load as the reference and calculate (a) the line currents IA, IB, and Iec: (b) the line volt- ages at the source, Vabs Vbes and Vea; and (c) the internal phase-to-neutral voltages at the source, Vans Vans and Ven V₁'n Zga Ven + V₁'n Zeb Zec a Zla LA I, Zo n N b Zib 115 Z₁c L B ZB ZA Zc
