Transformers with Scott - connection

Transformers with the "Scott" connection are used wherever there is a need for supply two-phase receivers or a group of single-phase receivers. An important advantage of Scott-connection is the fact that for the two-phase symmetrical load the three-phase network load is well balanced. Connection diagram and operation principle can be found in the "Technical guide"
