The critical information here is bolded, as follows: YNa0d1.
The upper-case Y indicates that the higher-voltage windings are connected in wye (or 'star'). The upper case letter N indicates an accessible neutral connection on the high-voltage side.
The lower-case 'a0' indicates an autotransformerwith an angular displacement of 0 degrees.
The lower-case d indicates that an auxiliary lower-voltage winding connected in delta (or 'mesh').
The numeral 1 is a multiplier of 30 degrees, and indicates the transformer connection's angular displacement(or 'phase displacement'). Angular displacement is expressed in multiples of 30 degrees, starting from 0 degrees.
So this is a wye-connected autotransformer having an angular displacement of 0 degrees with a delta-connected auxiliary winding having an angular displacement of 30 degrees.
i understand that YNaOd1 represent an auto transformer with HV winding as wye connected and loaded tertiary. Please correct me if i am wrong.

Dy1 means the vector group that is being used at a distribution system.
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.
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 ynd1
yes there is
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.
Dy1 means the vector group that is being used at a distribution system.
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.
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.
