A three-phase, 60Hz, wye-connected synchronous generator has balanced line-to-line voltages of 480V at its terminals. The generator is supplying power to two balanced and delta connected, three-phase loads. the first load is made up of three 15<-30 Ohm impedances, while the secound load is made up of three 18<50 Ohm impedances. Determine the following:
(a) Total (i.e.,equivalent) load impedance per phase (i.e.,line to neutral).
(b) The line current Ia at the generator terminal. use a phase voltage of Va=277.1281<0 V (since 480/(3^root) V =277.1281 V).
(c) The total complex power provideed by the generator.
