Please provide original new solution and dont confuse sequence
currents and phase currents. Positive sequence current is not phase
A current and negative sequence current is not Phase B current,
Part C of the question asks whats the fault current if Phases B and
C fault to eachother, not its sequences. Also is there a Negative
sequence in this question or no?
Problem 6 Consider the system shown in the single-line diagram of Figure 4. The required sequence reactances in per unit to the same base are as follows: G₁ X₁ X₂ = 0.12 G2 X₁ X₂ = 0.24 G3 X₁ = X₂ = 0.12 Transformers XT1= XT2= 0.12 Lines: Positive and X13-X12= 0.20 Negative Sequence a- Draw the positive-, and negative- sequence reactance diagrams. [6 Points] b- Determine the The'venin's equivalent of each sequence network as viewed from a fault in the middle of line 1-3. [7 Points] c- A line to line fault on phases B and C takes place in the middle of line 1-3. Determine the fault currents in phases B and C in per unit.
