Question 1 An unbalanced, 30, 4-wire, Y-connected load is connected to 380 V symmetrical supply. (a) (b) Draw the phasor diagram [6] 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: [12] Za = 45.5 L 36.6 22 Zb = 25.5 L-45.5 Zc = 36.5 L 25.5 22 Calculate the total wattmeter's reading (c) [2]
