Abstract
A transformer which is suitable for connecting with a compound network and renders possible shifting the phase angle of the secondary side-output voltage in relation to the primary side-input voltage. The secondary windings are divided into winding stages and there are provided lines and switches, by means of which these winding stages can be selectively connected in series. Since the phase angle of the voltage in each winding stage coincides with the angle of the corresponding winding, it is possible to vectorially add in this manner partial voltages with different phase angles, so that at the output terminal of one winding there appears a composite voltage whose phase angle is aligned in the same direction as said one winding or, in relation to such direction, is shifted through a predetermined angle value in clockwise direction or in counterclockwise direction.
