Solved by Expert David Morabito

Step 1

Starting with bus 1, we have: X1: Single-Phase, 50 MVA, 13.8 kV/132.8 kV, X = 6% The base voltage at bus 1 is 13.8 kV. Since this is a single-phase system, the line voltage magnitude at bus 1 is also 13.8 kV. Moving to bus 2, we have: X2: Three-Phase, 200 MVA, Show more…
