    Phase to Phase Fault calculation

    What would the correct formula to use to determine the multiples of a transformers rated OA current and then calculate into actual ampheres? Transformer: 10 MVA impedance 8.5% rated phase to phase voltage (secondary side) 12.47 kV Supply side capacity 650 MVA assume impedence angles are the same...
