A balanced ∆-connected load is fed by a three-phase supply for which phase C is open. Phase-A and phase-B are carrying a current of 100∠0∘ A and 100∠180∘ respectively. Find the symmetrical components of the line currents. (Note that zero-sequence currents are not present for any threewire system or ∆ system)
