In the vector group representation for this transformer, the letter 'y' represents a wye- or star-connection, and the letter 'd' represents a delta- or mesh-connection (I have no idea what 'n' stands for -anyone?). An upper-case letter indicates the higher voltage, while a lower-case letter represents the lower voltage. The sequence of the letters indicates the primary and the secondary windings. So the transformer in question is a wye-delta connection (presumably the 'y' should have been capitalised, meaning that this is a step-down transformer: i.e. Yd11).
The number appearing after the letter group (in this case '11') is a multiplier of 30o and indicates the transformer connection's angular displacement (or phase displacement). In this case, the angular displacement is 11 x 30o = 330o.
As angular displacement is defined as 'the angle by which the secondary line voltages lag the primary line voltages', this means the secondary line voltages of this particular transformer lags its corresponding primary line voltages by 330o.
So, to draw the phasor (not 'vector') diagram for this particular transformer, you would start by drawing the phase voltages (VAN, VBN, and VCN) of the primary wye connection (using VAN as the phasor of reference), from which you would then construct the corresponding line voltages (VAB, VBC, and VCA). To finish the diagram, you will then draw the secondary delta phasor diagram, starting with Vab lagging VAB by 330o (or, if you prefer, leading by 30o), then drawing Vbc and Vca displaced by 120o.

Why generator transformer vector group is YNd1 or YNd11 with the generator connected to Delta side?
Vector groups are used to categorize high and low voltage in transformers. The group number identifies the phase angle between configurations.
What is importance of vector group of transformer?
The vector group of a transformer is important for determining the phase relationship and polarity of the transformer windings. It helps ensure proper operation and connection of the transformer in the electrical system. Additionally, the vector group is essential for parallel operation of transformer units to avoid phase shifts and ensure synchronization.
How is a resultant drawn on a vector diagram?
A resultant on a vector diagram is drawn by connecting the tail of the first vector to the head of the second vector. Then, the resultant vector is drawn from the tail of the first vector to the head of the second vector. The resultant vector represents the sum or difference of the two original vectors.

What is the significance of vector-grouping in Power Transformers?
Vector group of Transformer: a.)The three stage transformer windings can be joined a few ways. In light of the windings' association, the vector gathering of the transformer is resolved. b.)The transformer vector gathering is shown on the Name Plate of transformer by the producer. c.)The vector gathering shows the stage contrast between the essential and auxiliary sides, acquainted due with that specific setup of transformer windings association. d.)The Determination of vector gathering of transformers is imperative before uniting two or more transformers in parallel. On the off chance that two transformers of diverse vector gatherings are associated in parallel then stage distinction exist between the optional of the transformers and huge coursing current streams between the two transformers which is extremely impeding.

Why mentions the nameplat of transformer in vector group?
A transformer's 'nameplate' lists all the data necessary to identify the rating, connections, etc., of a transformer. Part of this data is the 'vector group' information which applies to three-phase transformers, and which, in simple terms, tells us whether or not the transformer can be connected in parallel with another.
