Hi,
while parameterisation of a three winding transformor I would like to account its short circuit impedances.
Where in the transformer menu can I enter this value?
I highlited the specific values.
In PSCAD there is a"positive sequence reactance". Does the parameter correlate with the short circuit impedances?
If yes, how can I convert the short circuit impedances into the positive sequence reactance?
Sincerely,
Richard Hesse

because a transformer tends to be an inductive load it can consider the part of the resistance as zero and the percentage of the impedance would be the percentage of the data plate divided by 100.
example:
%Z 14
R= 0
JxL = 0.14
