A three-phase, four-wire unsymmetrical supply, with a phase sequence of ACB, supplies loads which are unequally distributed between the three phases. An analysis of the currents flowing in the direction of the loads shows that in line A, the positive phase sequence current is 24.5 ∠45° A and the negative phase sequence current is 12.5 ∠105°A. The current flowing back in the neutral is -j27 A. Determine the zero-phase sequence current (Iao) in line A in polar form. Determine the current (Ia) flowing in phase A of the load in polar form Determine the current (Ib) flowing in phase B of the load in polar form. Determine the current (Ic) flowing in phase C of the load in polar form.
