#2. In the 3-phase power system shown in Fig.2, the delta connected load is supplied through a short transmission line whose impedance $Z_{line} = (0.1 + j5)$ Ohms. If the load impedance $Z_{Load} = 4.5 \angle 36.87^\circ$ Ohms per phase and the load voltage $V_{bc}(t) = 208 \sin (wt - 120)$ V
Find (i) the phasor currents $I_A$, $I_B$, and $I_C$ in the lines.
(ii) $V_{AB}$, the phasor voltage at the source.
(iii)the real power P and the reactive power Q of the load.
#3. For the 3-phase power system shown in Fig. 3, the load is 30 kVA at a p.f. of 0.94 lagging. If the phasor load voltage, $V_{ab} = 480\angle 0^\circ V$
Compute: (i) The phasor line current, $I_a$.
(ii) The phasor voltage $V_{ac}$ of the source.
