5 6 IDB IBC 30° 30° ICA 30° IAB A balanced three-phase A-connected load is fed from a balanced three-phase circuit. The reference for the b-phase line current is toward the load. The value of the current in the b-phase is 12/65° A. If the phase sequence is negative, what is the value of IAB? The line voltage VAB at the terminals of a bal- anced three-phase A-connected load is 4160/0 V. The line current Iд is 69.28-10° A. a) Calculate the per-phase impedance of the load if the phase sequence is positive.
