A 3-phase , 4 wires balanced supply with BCA phase sequence issupplying the following loads connected in each phase:
Phase A:20kVA at 0.8 power factor laging.
Phase B:10kVA at 0.8 power factor leading.
Phase C:10kVA at unity power factor.
Find the line currents, load impedance connected in each phase andthe overall power factor of the system. Given that VAB =20.8kV(angle -30).
