Using the transformer ratings as base quantities, work Problem 3.14 in per-unit.

Problem 3.14

A single-phase 50-kVA, 2400/240-volt, 60-Hz distribution transformer is used as a step-down transformer at the load end of a 2400 -volt feeder whose series impedance is $(1.0+j 2.0)$ ohms. The equivalent series impedance of the transformer is $(1.0+j 2.5)$ ohms referred to the highvoltage (primary) side. The transformer is delivering rated load at a 0.8 power factor lagging and at a rated secondary voltage. Neglecting the transformer exciting current.
