4.26 A single-phase load is supplied through a 34.5-kV feeder and a 34.5/2.4-kV transformer. The feeder has an impedance of 50 +j180 ohms, and the transformer has an equivalent impedance of 24 +j120 ohms referred to its high-voltage side. The load takes 260 kW at 2.3 kV and 0.866 lagging power factor. a. Find the voltage at the primary side of the transformer. b. Determine the voltage at the sending end of the feeder. c. Calculate the real and reactive power input at the sending end of the feeder.
