(a) In a 3-phase, 4-wire system, the currents are in the A, B, and C lines under abnormal conditions of loading were as follows:
IA = 100/30° A, 1b = 50/300° A, and Ic = 30/180° A
(i) Calculate the positive, negative, and zero-phase sequence currents in the A-line.
(ii) Calculate the return current in the neutral conductor.
(b) Check by sketching IA, IB, and Ic as the sum of the appropriate symmetrical components.
