Can I parallel YNyn0(d11) with YNyn0(d1)

[tayyab1020]

I want to parallel two tranfrormers. Both 132/33KV YNyn0, 75MVA but their tertiary windings are different d11 and d1 respectively. Can somebody tell me if it is possible to parallel these. In my opinion since the power windings are having the same vector group, it must possible to connect these in parallel.

Thanks

The wyes can be paralleled, the deltas cannot be paralleled.

deltas are not feeding any circuit but only closed loop. Power circuit is only YY
