Answer b and c? Q1 (a) A balanced delta connected load of (10 + j3)N is connected to a 3-phase,415V,50HZ supply.Draw the circuit diagram, indicating VRN, VRY and all line currents, andfrom this calculate:(i)(ii)(iii)The 3 load phase currents (IRY, IYB and IBR).The 3 line currents (IR, Iy and IB).The total real power and power factor at the 3 phase supply.An unbalanced 4 wire star connected load consisting of the phaseimpedances ZRs (15+j5)N, Zys (10+j0)N and ZBs (18-j6)N is connected to a3-phase, 440V, 50H7 supply. Draw the circuit diagram ineluding theimplementation of a 2 wattmeter power measurement and from this:(b)(i)(ii)Calculate the 3 line currents (IR, Iy and IB).Construct a scaled phasor diagram and using this or otherwisedetermine the star/neutral current IsN. Include VRY and VRB onthe phasor diagram.Calculate the necessary wire diameter for the star/neutralconnection to achieve a current density of 3A/mm².(ii)(c)Determine the total real supply power (W) for Q1(b) based on the 2wattmeter measurements.
