An unbalanced, 3Ø, 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 ∟36.6 Ω
Zb = 25.5 ∟-45.5 Ω Zc = 36.5 ∟25.5 Ω [18] (b) Calculate the total
wattmeter’s reading [2]
