Polarity of 3p core transformer

[Amith Menon]

I have a 380V,3 phase core type transformer which is being used as AC line choke in the incomer of a VFD.As we are using only the inductance property of the transformer,I was just wondering whether we could connect R phase of the supply to any winding and then follow the phase sequence accordingly.
Thanks in advance

Welcome to the PF.
Yes. The only important thing is to make sure that the three windings are consistent and that one is not swapped end for end. For balanced phase currents, the shared core should have a sum zero field.
