Draw the pu positive-, negative- and zero-sequence impedance networks. Find the Thevenin impedances as viewed at bus 3. If a single line-to-ground fault with a fault impedance of j0.05 pu occurs at bus 3, calculate the subtransient fault current to the ground and the phase voltages at bus 3. If the fault were a line-to-line fault with the same fault impedance, what would be the fault current?
