- 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. If a three-phase wye load draws 3/4 of the nominal current of the 300 MW system with FP = 0.85 lagging and at 230 kV, calculate: (a) Current at the load in KA (b) Voltage at the source in KV, (c) Current at the source in kA and (d) power at the source in MVA.
