it is a star to star connected transformer. It having two neutrals. One is at Primary side and another is at secondary side to balance the loads.
Y= Primary star connection
N=Primary Neutral
y=secondary star connection
n=secondary neutral
and
0=No phase shift between primary and secondary.
So,finally this meaning is star to star connected with two neutrals and zero phase displacement.
Please refer below i detailed some notations to calculate any other vector groups
D= Primary Delta connection
d=Secondary Delta connection
a=Auto transformer
Z=Zig zig connection
11=30 degrees phase shift b/w primary & secondary
1= 30 degrees phase shift b/w primary & secondary
1) Consider capital letters for Primary notations
2) Consider small letters for secondary notations
3) Consider Clock reference at 12.00 for calculation of degrees
I think this procedure is very useful to calculate for other vector groups.

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.
In series, yes. In parallel, nope! Putting a Yd1 transformer in series with a Dy11 transformer would result in the output of the Dy11 transformer being identical to the input of the Yd1 transformer with the exception of the voltage magnitude - this will change depending on the winding ratio's on both transformers. But, in regards to other properties of the voltage, the phases will in be in phase, with the voltage in-between the two transformers lagging by 30 degrees.
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.

Dy1 means the vector group that is being used at a distribution system.

i understand that YNaOd1 represent an auto transformer with HV winding as wye connected and loaded tertiary. Please correct me if i am wrong.
Vector groups are used to categorize high and low voltage in transformers. The group number identifies the phase angle between configurations.
Vector group means it defines the primary & secondary side connection type of the transformer.For example DY says D for the delta connections (windings connected between two phases) & Y for the star connections (windings connected between two phases). That's why identification of the vector group of transformer is important.AnswerVector groups specify whether two or more three-phase transformers can be paralleled with each other. In order to do so, their angular displacements must be the same. Transformer connections listed in the Vector Group tables, categorise transformer connections in terms of their angular displacements.

This is basically to reduce the harmonics injected back in the grid which are generated because of the controller rectifier circuit (Thyristor Bridge - B6C) after the transformer secondary.
