pg. 437) An acb sequence balanced three-phase Y- connected source supplies power to a balanced, three-phase A-connected load with an impedance of 12+j90/6. The source voltage in the b-phase is 240/-50° V. The line impedance is 1+j10/p. a) Draw the single-phase equivalent circuit for the a-phase. b) Use this drawing to find the current in the a-phase of the load.
