A three-phase transmission line supplies power to three loads at a voltage
408 Vrms (line to line). The loads are as follows:
Load 1:
S₁ = 100+ j50 VA
Load 2:
S₂ = 40-j20 VA
Load 3:
S3 = 10 + j0 VA
Find the magnitude of the line current | Line and the combined power factor of

- A 60 Hz, 230 kV, 275 km long, uncompensated three-phase transmission line consists of three conductors bundled by phase, such that each conductor in the line is of the ACSR Falcon type. The separation between each bundled conductor is d = 45 cm and the separation between each phase of the line is 2.4 m. Calculate: "The parameters R, L, C of the line in Q2/km; µH/m and nF/m. And the total values of ZL and YC in Q and S, respectively, and in polar coordinates." Generalized constants A, B, C and D of the line, according to the type of transmission line. Present the results in rectangular coordinates.
