You must show all the work and all sequence networks needed to get these numbers.
For the radial power system shown in table, calculate the line-to-ground fault current flowing in each of the CBs for faults at each of the buses. The system data are given in the accompanying table. Also determine the corresponding faulted phase voltage, assuming that the generator is ideal, with a terminal voltage of 1.0 pu.
