WebAug 3, 2007 · If you put the vector-diagram of a Dyn1 next to a Dyn11, you'll notice that the two is mirror images of each other. Thus, by changing the phase rotation (swapping two phases) on both sides, (From ABC to ACB and abc to acb) you'll change the vector group from a Dyn1 to a Dyn11. Unfortunately it is difficult to explain without drawings.
WebAnswer (1 of 8): Vector Group.
