Find the inductive reactance per mile of a single-phase line operating at 60 Hz. The conductor used is Partridge, with 8 ft spacing between the conductor centers.
For the following balanced-Y systems, if the phase voltage at source V = 13.8 kV, and the impedance at the load is 500 Ω. Assume a balanced system. Calculate the phase current at the source side: 6.78 A, 11.43 A, 9.2 A, or 7.81 A.
