In Figure 1, the 3-phase source has a line-to-line voltage of 440 volts. The details of the impedances are the following: Z₁ = 36-j15; Z₂ = 40 + /300 Z=45+j600; Z4 = 75+ j0; Z5 = 50+ j50 ; Z6 = 20 + j48 2. Determine the following: (a) Line currents: labi, and lei; (b) Line currents: Iaz, Ibz, and Iczi (c) Line currents: lar, Ibr. and ICT; (d) PT, QT, ST, and pfr for the system; (e) W, and W, readings for 2-wattmeter method at lines a and b.
