There are normally four vector groups weriten on generator
name plate, DY0, DY11, DY1 and DY6. DY means delta on H.V
and Y on L.V side. the number with this means the phase
displacement between input and output. 0 means no phase
displacement, 1 means -30 degree and 11 means 30degree and
6 means 180 degree it is according to the clock
revolution.vector group must b same for parallet operation.
