Afault occurs at bus 1. ignore phase shift and perform the following computations: a. draw the sequence network diagrams (positive, negative and zero) and find the thevenin equivalent for each sequence network at bus 1 where the fault occurs. (30 pts) b. connect the thevenin equivalents for a single line to ground fault on phase a at bus 1 and find the fault current. also find the bus voltages after the fault.(35 pts) c. connect the thevenin equivalents for a double-line-ground fault at bus 1 and comp
