1) 1 T2 T2 4 Machine 1 Machine 2 Kroon AK YA Two synchronous machines are connected through three-phase transformers to the transmission line shown in below fig.The ratings and reactances of the machines and transformers are Machines 1 and 2: 100 MVA, 20 kV; X"₁ = X₁ = X₂ = 20%, X₁ = 4%, X = 5% X = 8% Transformers 7, and 72: 100 MVA, 200/345Y KV; X, On a chosen base of 100 MVA, 345 kV in the transmission-line circuit the line reactances are X₁ = X2 = 15% and X₁ = 50%. Draw cach of the three sequence networks and find the zero-sequence bus impedance matrix by means of the Zhus building algorithm. Find the fault current if L-G fault occurs at the terminals of Machine2.
