A balanced Y-connected load-1 has Z LN1 = 4 + j1 in each phase of Y.

A balanced Y-connected load-1 has Z_LN1 = 4 + j1 Ω in each phase of Y. It is connected in parallel with a balanced Δ-connected load-2 with Z_LL2 = 12 + j6 Ω in each phase of Δ. If these two parallel loads are powered by a three-phase, Y-connected generator with a 480-V line voltage, determine the line current at the generator terminals and the real power delivered by the generator.
