<p>PURPOSE:To provide a three-phase transformer with which a neutral point can be provided on a delta winding without impairing the symmetrization with respect to the neutral point. CONSTITUTION:A tertiary winding C3w, having the number of turns two/thirds of the number of turns n2 of secondary windings C2u to C2w, is provided in a phase. The tertiary winding C3w is connected between taps 2ut and 2vt led out respectively from the position of (2/3)n2 turn from the mutually-connected secondary windings C2u and C2v of the other two phases, and the mid-point O is led out from the mid-point of the tertiary winding C3w.</p> |
