Consider the circuit given below, where a three-phase synchronous generator having short circuit capability of 600 MVA, connected to 115kV bus and A-Y transformer 30MVA and 13.8 kV bus. The transformer has impedance 10% at 30MVA, and also positive sequence and negative sequence impedances as 10% at 30MVA. Consider ONE line to ground fault (1LG) at 13.8 kV bus. Thus, perform the Fault Analysis and find the three-phase current and voltage values.
