Problem # 3| U.Q | Symmetrical Fault Analysis using Thevinen's theorem | PSA Generator G1 & G2 are identical and rated as 11 KV,30 MVA have a transient reactance of 0.3 pu at own MVA base. The Transformers T1 & T2 are also identical and are rated 11/66 KV, 10 MVA and have a reactance of 0.075 pu to their own MVA base. Then the line is 60 KM long each conductor has a reactance of 0.92 ohms per km. The three phase fault is assumed at point F which is 25 km from Transformer 1.Find the short circuit current.
