Satya Dev

Answer / ranjan

Mostly we use Dyn11 & Ynd1 Vector group & more vector groups are related to the grid .

Answer / sudeep dutta

it depends on wheaher the transformer ins step-up or step-
down....................



For step-up .........it should be Yd1 or Yd11 .........
For step-down it should be Dy1 or Dy11............
for grounding purpose it should be Yz1 or Dz11........

Answer / shivendu

Ynd1 and Dny1 and Ynz1 is the normal vector group used for
transformer construction.

Answer / dhaval

dyn11 dynl

Answer / c.ashok kumar

For Distribution Transformers we can considered the vector
grouph for same as DZn0. Which reduce the 75% of hormonics
in secondry side.

For power transformer we can considered the vector group
deponds on application.
for example: Generating transformers: DYn1
furnuse transformers: YnYn0

Answer / raviteja.n

The vector group used for design of transformer purely
depends on voltage levels of primary and secondary and also
purpose of it.
