Unbalanced loads are connected to a balanced three-phase four-wire 50 Hz 400 V supply in star configuration. The symmetrical components, lo, ₁ and /₂, of unbalanced line currents are given as: :10.51-176.13° A /1: 20.66210.88° A 12: 9.962-18.62° A Assume that the transmission line has negligible impedance. Calculate: (i) The line currents. (ii) The resistance and inductance (or capacitance) of each load, Za, Zb and Zc.
