Q6/ Consider an electrical system shown in figure below. It delivers rated load with 0.8 p.f lagg. when a single line to ground fault occurs through impedance \(\left(Z_{f}=j 0.1\right.\) p.u) at \( F \). When the fault cleared, CB3 and CB4 are opened. Find the critical clearing angle and critical clearing time:
