Make sure you have sequence data.

If you do not have any information on the sequence impedance, it would be impossible to determine.

If you do have the Thevenin sequence impedance at the particular bus you are applying a fault (and let's say not for anywhere else in the network), you can emulate a bolted single-phase fault by setting the impedance value to the sum of the negative and zero sequence components of the Thevenin impedance, and apply a three-phase fault.

hello I thanks that your simulation model is wrong (verify if you have the sequence data).
