Q4: A balanced three phase (Y-A) system, the delta load connected to a balanced three phase source of stare connection. The apparent power of each phase impedance of the load is 80 KVA with lagging power factor of (0.8). If one of the phase voltages of the source is Van = 200 230 Vms, the angle of VAB is located at (0), then determine the following: a) IcA (Arms). b) The sequence of this three-phase system? c) VCA (Vms). d) Vbn (Vrms). e) Total average power absorbed by the load.
