Transformer Requirement

3-PHASE

Vector-group logic: a Dyn11 secondary sits at −30° (clock 11). A second leg must be 30° away → a clock-0 unit (Dd0 / Yy0). For a single dual-secondary unit the two LV windings are inherently 30° apart (Dd0yn11). Verify impedance, tap range, BIL and neutral treatment against the actual site supply and converter datasheet before issuing.
