Course name: Power System ICourse Code: EE 314Term: Spring 2020Transformer Homework01/04/2020Solve all the questions using Microsoft Word and upload the word file.Question 1:A single-phase two-winding transformer is rated 20 kVA, 480/120 V, 60 Hz. A sourceconnected to the 480-V winding supplies an impedance load connected to the 120-Vwinding. The load absorbs.lagging when the load voltage is 118 V. Assume that thetransformer is ideal and calculate the following:a.The voltage across the 480-V winding.b.The load impedance.c.The load impedance referred to the 480-V winding.d.The real and reactive power supplied to the 480-V winding.
d)S1and S2= 12000+j9000
