4. In a power system, a 2.4-kVA, 480/240-V, 50-Hz transformer has the following parameters as referred to the primary side: R₂1 = 3 02, Xe1 = 402, Rc1 = 2.5 k 2, and Xm1= 2 k Q. The transformer is operating at full load with a power factor of 0.8 leading. Determine the efficiency (n) and the voltage regulation (VR) of the transformer. Use the approximate equivalent circuit as seen from the primary side below. V R₁ 110 ele jXml R₁ jX₁ voo ²2₁ V₂=aV₂
