PURPOSE:To facilitate a phase regulating method by connecting two or more single-phase loads between the teaser windings of a Scott transformer. CONSTITUTION:A Scott-connected transformer 1A has main windings 7', 9 and teaser windings 7, 8. A single-phase load 11, a capacitor 12 for forming a main winding balancer and a switching unit 6 are connected between u and thetaterminals of winding 9. A single-phase load 10, a capacitor 12 for forming a balancer and a switching unit 6 are connected between v and theta terminals of the winding 8. The relationship between the load currents of the main wind ing side and the teaser winding side of the secondary side of the transformer 1A and the primary winding current is balanced at the primary side to flow a balanced current if the loads of the main and the teaser sides have the same magnitude. |
