WebNov 1, 2014 · When the load side (LT) suffers some dip the LT current try to go out of phase with HT current, so 30 degree phase shift in Dyn-11 keeps the two currents in phase when there is dip. So the vector group at the generating station is important while selecting distribution Transformer. Vector Group in Generating-Transmission-Distribution System: Webtransformer is indicated by a vector group symbol. This symbol indicates the winding con-nections and their relative phase displacement by means of a nume-rical index (e.g. Dny11). The "clock method" is used to produce the numerical index of the vector group, with each hour representing 30 electrical degrees.
