Modellilng the zero phase sequence impednace in PTW32 software of a YN d11 d11 transformer

[EddyWirbelstrom]

It is required to model a three phase, three limb, core type transformer with connection YN d11 d11 in the software PTW32.
Measured impedance values are shown shaded in green in the attached excel spreadsheet.
Question:
How are the following transformer zero sequence impedances modelled :
 zo ps Primary-Secondary,
 zo pt Primary-Tertiary
 zo st Secondary-Tertiary ?
Tab <3-Wndg-Xfm_Measured Data> includes transformer measured impedance values.
Tab <Star Equiv cct for zo> includes calculations attempting to determine zo ps, zo pt, zo st.

I would just send SKM Tech Support your transformer data and ask them to come up with the best model in PTW. Shouldn't be any charge to you if you are on maintenance.
