transformer short circuit calculation wrong results

im doing school project for calculating short circuit and i calculate next example.

 but i get wrong results peak current around 50kA but there should be around 75kA.

Hello Uros,

this is most likely and issue with some of the model parameters if it is actually giving you the wrong result here, but correct results elsewhere. In other words, if the simulation seems to be working for all the other scenarios but this one, it is most likely the wrong data was put into the simulation. You will need to share your models and parameter list seperate from the model and how you calculated that 75kA was the correct answer to get more detailed help.
