The open-delta connection it is actually 2 single phase transformer in series.
The voltage between two high voltage terminals it is 6600 V and each secondary
phase presents 110/√3 V.
If all three H.V.phases are connected the voltage between secondary terminals[in series] is 110/√3<0o -110/√3<120o=110 V<30o .
If the removed phase it is an extreme one then only one transformer stays connected [two voltages at ends] and the voltage is 110/√3 V.
If the removed phase it is the middle then both transformers stays connected with only one 6600 V and the voltage is 2*110/√3/2<0o=110/√3 V.
