For the configuration shown in figure, the breaker connecting a large system to bus 2 is initially open. The system 3-phase fault level at bus-3 under this condition is not known. After closing the system breaker, the 3-phase fault level at bus 1 was found to be 5 p.u. What will be the new 3-phase fault level at system bus 3 after the interconnection? All unit values are on common bases. Per fault load current are neglected and pre fault voltages are assumed to be 1.0 p.u. at all buses.
