Given a balanced three-phase system, the source is wye-connected with the voltage 600V, the impedance of the line between the source and the load is j1Ω/phase, and the load is delta-connected with the impedance 12+j9 ohm/per phase.
Draw both three-phase and per phase circuits
Calculate the voltage phasor at the load terminal with the phase angle
Calculate the complex power absorbed by the load and its angle
Just need to know how to solve this, no drawing necessary. The answers are 530V at an angle of 22 degrees, and 56.2 kVA at an angle of 36.9 degrees.
