Fault level withstand capacity
WebIn this case, the available fault current at the primary terminals is 31.4 kA. For a fault on the secondary side of the transformer, the transformer impedance will limit the fault current that flows in the primary to 1.8 kA in the lines and 1.1 kA in the coils – significantly lower than the available fault level.

If we calculate the equivalent current at 350 MVA we find, Isc = 350 / (1.73 x 10) = 20.2 kA rms. The difference depends on how we round up the value and on local habits. The value 19 kA rms is probably the most realistic. can you bring a dog to target
