Two balanced Y-connected loads in parallel are supplied by a balanced, three-phase, 480-volt (line-to-line) source. One load draws 15 kW at 0.6 power factor lagging, and the other load draws 10 kVA at 0.8 power factor leading, a) Draw the power triangle for each load and for the combined load. b) Determine the power factor of the combined load and state whether lagging or leading. c) Determine the magnitude of the line current from the source. d) D-connected capacitors are now installed in parallel with the combined load. What value of capacitive reactance is needed in each leg of the D to make the source power factor unity
