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.

What does (d) means in the vector group YNyn0(d)?
In the vector group notation YNyn0(d), the "(d)" indicates the phase displacement between the primary and secondary sides of the transformer. Specifically, it denotes a phase shift of "d" degrees, which is typically a specific value like 30, 60, or 90 degrees. This phase shift is important in determining how the voltages and currents are related between the two sides of the transformer, impacting the overall performance and application of the transformer in a power system.
What are the condition for checking vector group of YNd1 power transformer?
what is ynd1
Is there any relation with vector group of transformer with power factor?
yes there is
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.
Can a Dy11 vector group transformer be connected to a Yd1 vector group transformer source?
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.

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.

What is the purpose of dzn10 vector group?
The purpose of the dzn10 vector group is to indicate the phase displacement relationship between the primary and secondary windings of a transformer. This information is crucial for ensuring proper connection and operation of the transformer in a three-phase electrical system. The dzn10 vector group specifically represents a 0-degree phase shift on the secondary side compared to the primary side.
Can a Dy11 vector group transformer be connected to a Yd1 vector group transformer source?
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.
What is the meaning of suffix YNaOd1 in vector group of transformer?
i understand that YNaOd1 represent an auto transformer with HV winding as wye connected and loaded tertiary. Please correct me if i am wrong.
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.
