5. Determine the sequence components if $I_a = 10\angle60^\circ A$; $I_b = 10\angle-60^\circ A$; $I_c = 10\angle180^\circ A$. 6. The line b of a 3-ph line feeding a balanced Y-load with neutral grounded is open resulting in line currents: $I_a = 10\angle0^\circ A$ & $I_c = 10\angle120^\circ A$. Determine the sequence current components. 7. Given $Z_0 = 0.199\angle90^\circ pu$, $Z_1 = 0.175\angle90^\circ pu$, $Z_2 = 0.175\angle90^\circ pu$, compute the fault current and voltages for a Three-phase fault. 8. For the following power system network shown in the figure, the specifications of the component are as follows: G1: 25 KV, 100 MVA, X=9% G2: 25 KV, 100 MVA, X=9% T1: 25/220 kV, 90 MVA, X=12% T2: 220 KV/25 kV, 90 MVA, X=12% Transmission Line 1: 220 KV, X=150 ohms Choose 25 KV as the base voltage at the generator G1 and 200 MVA as the MVA base. Solve for the per unit reactances.
