Question 1 An unbalanced, 30, 4-wire, Y-connected load is connected to 380 V symmetrical supply. (a) Draw the phasor diagram and calculate the readings on the 3-wattmeters if a wattmeter is connected in each line of the load. Use Ebn as reference with a positive phase sequence. The phase impedances are the following: Za = 45.5 L 36.6 12 Zb = 25.5 L-45.5 22 Zc = 36.5 L 25.5 22 [18] (b) Calculate the total wattmeter's reading [2] - =
