For a circuit with a synchronous generator serving a Δ-connected load through a transposed transmission line, how can the load voltages be easily determined using symmetrical components? Multiple Choice: a. Solve the positive sequence circuit only. The load voltage there will be the a-phase load circuit for a balanced set. b. Solve each decoupled sequence circuit individually, and then multiply by the A-1 matrix to get the phase values.      c. Symmetrical components will add to the complexity of this problem.
