A three-phase balanced wye connected source with a line voltage of 400v supplies a balanced delta connected load with the impedance of each phase ?∆ = 60∠450Ω. The impedance of the threephase line connecting the source and the load is ?l = 2∠300Ω/phase. Calculate the line current and phase current magnitudes of the load. Also find real and reactive power at the terminals (abc) of the load and at the terminals (ABC) of the source.
