What is the significance of vector-grouping in Power Transformers?

Answer 1

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.

Answer 2

Vector groupings are categories of angular displacement that determines which types of three-phase transformer connections enable them to be paralleled with each other.
