A 1.5 KVA, 220/120 V, 60Hz real step-down transformer has the following parameters that are all referred to the primary-side: the total copper loss R = 2.4 Ω, the core loss Rc = 2.4 KΩ, the magnetization reactance Xm = 2 KΩ, and all the leakages are negligible. Suppose that the output port in the secondary-side is operated at full-load and rated voltage with the unity power factor p.f. = 1.

(a) Find the power factor p.f.1 at the primary-side input port;

(b) What is the voltage regulation (V R)?

(c) Determine the power efficiency η .
