Two alternative models for a single phase transformer are shown in Figure 1. "Model A" shows the leakage and core elements referred to the 'H' side, while 'Model B' shows them on the "X" side. This is a 24 kVA, 8 kV to 240 V, RMS transformer. + VH + V H RH www ele XH m ell ell www ell Xx RC ell Rx www + Vx + V X FIGURE 1. Two Transformer Models Model A Model B (a) If the core absorbs 100 W and 1000 VARs, what are the core elements Re and Xc if they are located: (1) If it is on the H side: R (Model A)? (2) If it is on the "X" side: Rx (Model B)? (c) If XH = 133 in Model A, what is Xx in Model B? (1) On the "H" side (Model A)? (2) On the "X" side (Model B)? (b) If, when running at rated current, the copper loss is 1,200 W, what is the series resistance element
