What is vector group YNd11?
Vector Group of Transformer: Common Symbol Designation Vector group of Transformer Notation. This configuration belongs to the vector group of transformer Dyn1 where the LV lags the HV by 30°. Figure 4. Delta primary, wye secondary with neutral. The LV lags the HV side by 30°.
What is the vector group of distribution transformer?
The vector group indicates the phase difference between the primary and secondary sides, introduced due to that particular configuration of transformer windings connection. The Determination of vector group of transformers is very important before connecting two or more transformers in parallel.
What is the lag in a ynd11 transformer?
In any ’11’ configuration the LV winding leads the HV winding by 30°. In a YNd11 transformer the delta winding leads the star winding by 30°, so if you use the delta winding as the reference then the star winding has a 30° lag. RE: Simple question about vector group YnD11 ?
