transformer short circuit calculations

[tiger79]

i am working in substion design, now a days i am working on three winding power transformer short circuit calculations.If someone have short circuit calculation excel sheet/software or some tips. Please share with me.

Single winding on the primary the source side, dual windings on the secondary the load side. If you know the pair impedance values, do it per pair wise, no difference than regular transformers.

But only YYY and YYD available. In addition, be very careful with the impedances.
