SOLVED:In a balanced three-phase system, the source has an a b c -phase sequence and is connected in delta. There are two parallel wye-connected loads. The phase impedance of load 1 and load 2 is 4 j 4 Ωand 10 j 4 Ωrespectively. The line impedance connecting the source to the loads is 0.3 j 0.2 Ω. If the current in the a phase of load 1 is 𝐈A N1=10 ∠20^∘ A rms, find the delta currents in the source.

A balanced three-phase distribution line has an impedance of 1 j 5 Ω/ ϕ. This line is used to supply three balanced three-phase loads that are connected in parallel. The three loads are L1=75 kVA at 0.96 pf lead, L2=150 kVA at 0.80 pf lag, and L3=168 kW and 36 kVAR(mag- netizing). The magnitude of the line voltage at the terminals of the loads is 2500 √(3) V a) What is the magnitude of the line voltage at the sending end of the line? b) What is the percent efficiency of the distribution line wit
