2 Short Circuit Level(8 points) Figure 2 (a) shows an 400 kV power system contains two substations A, and B having fault levels of 40 GVA, and 30 GVA respectively. The

system is to be reinforced by two lines each of reactance j4 2 connecting together the two substations as shown in Figure 2(b). Calculate the new fault level at A and B substations in GVA. Neglect resistance. Use Only Zbus Figure 2 A !! Li 1000 (a) (b)
