A short transmission line connects a step-up transformer on the source side with a series impedance of j0.5 ohms (referred to the primary) to a step-down transformer on the load side with a series impedance
of 50 ohms (referred to the primary). The turn ratio of the step-up transformer is 1:10 and a no-load primary voltage of 23 (line-to-line) kV. The step-down transformer has a turn ratio of 35:2 and it has a Y-
connected, balanced load of 0.490 +ị 0.0816 ohms connected to its secondary side.
A capacitor bank of -j0.171 ohms is added parallel to the load. Assuming an ideal transmission line, the load voltage (line-to-neutral) would be:
O A, 7360 V
O B. None of the other choices are correct
OC. 4806 V
O D. 6.2 kV
O E. 12750 V
