Three loads with impedances j5 ohms, 10 ohms and-110 ohms are connected in Star with no neutral (isolated or ungrounded star). Assume a balanced positive sequence for the source voltages with phase voltage of 120 V connected in star. Take the source impedance and line impedance to be 0.4+10.3 ohm per phase and 0.6+ 10.7 ohm per phase, respectively. Determine the L Show the circuit connection and obtain the line currents and load terminal voltages (4) Power generated by the supply and consumed by each load. Show that the power balance equation is satisfied i.e. power generated power loss and power demand. [3] Draw the phasor diagram for the load side i.e. show load currents and voltages only.
