Vector Group Depends on the type of windings in Primary & Secondary of Transformer.
Let take one transformer example
Primary Winding is "Delta" (D)
Secondary Winding is " Star" (S)
Phase angle between two transformers is lag 30 degrees

Therefore : Vector group = DSn11

Where n= Neutral
11 = For 30 Degrees constant value

Ho de we calculate the line loss of a 500 kv line over 1000km.
