1. Draw a frequency domain diagram of a Y-Delta 3 phase circuit with the following parameters: a. Source voltages va(t) = 155.6-cos(377-t) b. Line Impedances ZaA = 3.77j c. Load Impedances ZA = 20 +22.6j vb(t) = 155.6-cos(377-t + 120deg) ZbB = ZaA vc(t) = 155.6-cos(377-t - 120deg) ZcC=ZaA ZB = 30 + 9j ZC = 50 + 20j 2. Calculate the overall efficiency of power delivery to the 3-phase load (total average power absorbed by load / total average power delivered by source). 3. Calculate the power factor associated with each phase of the load (Z1, Z2 and Z3) 1. Draw a frequency domain diagram of a Y-Delta 3 phase circuit with the following parameters: a.
