3. The currents in a 3-phase unbalanced system are : IR = (80 +j0) A : The phase sequence is RYB. Calculate the zero, positive and negative sequence components of the red ly = (-10-j 60) A ; I = (70 +j 60) A line current and determine the current in the neutral wire. (g0 = 0A; Ig = 76-58 Z13°A; I = 18-12 -72-6 A; Iy=0A] 4. A 3-phase, 4-wire system supplies loads which are unequally distributed in the three phases. An analysis of the circuit shows that positive and negative phase sequence components of the current in the red line are as under :
