3-phase line, which has an impedance of 2 + j4 per phase, feeds two balanced three-phase loads that are connected in parallel. One of the loads is Y-connected with an impedance of (20 + j40) per phase, and the other is -connected with an impedance of (65-j40) per phase. The line is energized at the sending end from a 60-Hz, three-phase, balanced voltage source of 120 (3)^1/2 V (rms, line-to-line).
Determine:a) The current, real power, and reactive power delivered by the sending-end source. b.) The line-to-line voltage at the load. c) The current per phase in each load. d). The total three-phase real and reactive powers absorbed by each load and by the line.
