In Problem 3, do all analysis a) 3 phase fault at bus 2 and what is the actual fault current of each phase at the low voltage side of the transformer? b) In single phase ground fault, find the fault currents? c) Find the fault currents of two line to ground?

Solution

values of impedances , the internal impedance of the transformer are not provided.
