A 25-kVA, 2400 / 240-V, 60-Hz, single-phase transformer has an equivalent series impedance of 3.45+j 5.75 Ωreferred to the primary highvoltage side. The core loss is 120 W. When the transformer is delivering rated kVA to a load at rated secondary voltage and a 0.85 lagging power factor, find the percent voltage regulation and the efficiency of the transformer. | Numerade

A single-phase transformer operates from a 230 V supply. It has an equivalent resistance of 0.1 Ωand an equivalent leakage reactance of 0.5 Ωreferred to the primary. The secondary is connected to a coil having a resistance of 200 Ωand a reactance of 100 Ω. Calculate the secondary terminal voltage. The secondary winding has four times as many turns as the primary. | Numerade

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, determine (a) the voltage at the transformer
