QUESTION 3 In a delta star system the impedances of the load are as follows Zg -24.082 - 48.37°0; 25=25.52 48.18 and Zc-22.672 41.42 The load is supplied from a 50 Hz symmetrical, three phase supply Eab=4402-20° V with a phase sequence of ABC Use Millman's theorem and determine the phase voltage (Vas) of the load in polar form. Enter only the numerical value of the magnitude and not the angle: For instance, in the case of 253.7262.60.13º, enter only 253.726 QUESTION 4 In a della-star system the impedances of the load are as follows Za -24.082 - 48.37" ; 26-25.548.18 and Zc-22.672 41.420. The load is supplied from a 50 Hz symmetrical three phase supply Eab-4402-20° V with a phase sequence of ABC Use Miliman's theorem and determine the phase voltage (Vas) of the load in polar form. Enter only the numerical value of the angle and not the magnitude: For instance in the case of 253.726 260.13°V, enter only: 60.13º For angles in the 3rd and oth quadrant (that lie between 180 and 360° subtract 360° to get the negative coterminal angle In the case of 253.7262260.25" V=253.7262(260.25º-360° V =253.7262-99.75°. enter only: -99.75 QUESTIONS In a delta star system the impedances of the load are as follows Zg -24.082 - 48.37°0; Zb*25.52 48.180 and 2c +22.672 41.42° 22. The load is supplied from a 50 Hz symmetrical, three phase supply Eab-4402-20° with a phase sequence of ABC
