Given the open-delta VT connection shown in Figure 10.38, both VTs having a voltage rating of \(240 \mathrm{kV}: 120 \mathrm{~V}\), the voltages are specified as \(V_{\mathrm{AB}}=230 \angle 0^{\circ}, V_{\mathrm{BC}}=230 \angle-120^{\circ}\), and \(V_{\mathrm{CA}}=230 \angle 120^{\circ} \mathrm{kV}\). Determine \(V_{\mathrm{ab}}, V_{\mathrm{bc}}\), and \(V_{\mathrm{ca}}\) for the following cases:

(a) The dots are shown in Figure 10.38.

(b) The dot near c is moved to b in Figure 10.38.
