you access any transformer data sheet that describes three-phase transformers, you will come across either Dyn11 or Ynd11. Some other transformer data sheets might use different designations, but they all refer to the vector group of transformers. This means that a delta connection (\u0394) is employed for one side of the transformer while a wye connection (Y) is utilized for the other side. The delta-wye connection serves as the most popular transformer connection worldwide because it enables the transformer to perform two primary functions, which include increasing or decreasing voltage and creating a grounded neutral for the wye side.
