THREE-PHASE TRANSFORMER WITH ZERO SEQUENCE CURRENT COMPENSATION WINDING

摘要

A three-phase transformer having zero sequence compensation current winding comprises bars located at 120 degree one relatively to another, high voltage power windings AX, BY, CZ; low voltage windings ax, by, cz at every bar, and complimentary zero winding n'n. High-voltage power windings AX, BY, CZ and low-voltage windings ax, by, cz are starconnected. Zero winding is wound around the central bar and connected to the common point of low voltage winding ax, by, cz.
