we use Capital letters for the High Voltage ( Primary ) and we use small letters for Low voltage secondary so in this case:
YN: it's refer to High Voltage, and it means the high voltage connection is Star and Neutral is Brought out.
d: refer to Low Voltage and it means that low voltage connection is delta.
11: mean LV lead the HV by 30 degree.
and others number it will be like bellow
01 02 03 04 05 06 07 08 09 10 11 12
30 60 90 120 150 180 210 240 270 300 330 360 or 0

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.
Vector group of autotransformer?
YNyn0
How do you test Yyn0 vector group of transformer?
in electrical engineering
What does dy1 means in a power transformer?
Dy1 means the vector group that is being used at a distribution system.
Why is identification of the vector group of transformer important?
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.
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 the population of Vector Group?

Vector Group Ltd. was founded in 1910. It is a holding company that operates in the tobacco and real estate industries.
What is the symbol for Vector Group Ltd in the NYSE?
The symbol for Vector Group Ltd. in the NYSE is: VGR.

What is the difference between balanced and unbalaced forces?
The vector sum of a group of forces is zero. The vector sum of a group of forces isn't zero.
What is a fraction operation that creates groups of numbers?
if you take a vector (= group of numbers) and you divide it by a scalar (=one number) then you get a vector (=group of numbers)
What is the definiton of unbalanced forces?
A group of forces whose vector sum is not zero.
What is an affine group?
An affine group is the group of all affine transformations of a finite-dimensional vector space.
Will a vector multiplied by another vector result in another vector?
It depends on the angle between the vectors (AB). The product of two vectors Av and Bv is AvBv=-Av.Bv + AvxBv= |AvBv|(-cos(Ab) + vsin(AB)). If the angle is a odd multiple of 90 degrees the product is a vector. If he angle is an even multiple of 90 degrees, the product is a scalar. If he angle is not a multiple of 90 degrees, the product of a vector by another vector is a quaternion, the sum of a scalar and a vector. Most numbers in physics and science are quaternions, a combination of scalars and vectors.Quaternions forma mathematical Group, vectors don't. The product of quaternions is always a quaternion. The product of vectors may not be a vector, it may be a vector , a scalar or both. The product of scalars is also a Group. Vector by themselves do not form a Group. The Order of Numbers are Scalars form a Group called Real Numbers; scalars and a single vector form a group called complex numbers; scalars and three vectors form a group called Quaternions. These are the only Groups that provide an Associative Division Algebra.
