Response: Me neither :/

3. A 12.47 kV feeder provides service to an unbalanced wye-connected load specified to be: Phase a: 1000 kVA, 0.9 lagging power factor Phase b: 800 kVA, 0.95 lagging power factor Phase c: 1100 kVA, 0.85 lagging power factor a) Compute the initial load currents assuming that 60% of the load is complex power, 25% constant current, and 15% constant impedance. b) Determine the currents at the start of the second iteration if the load voltages after the first iteration have been computed to be 6851-1.9 VLNabcl69732-122.1V 68864 17.5
