.~.~ With interphase transformer in the supply circuit
DEFINITION
Classification: 315/142
(under subclass 141) Systems wherein the transformer means includes at least two sets of transformer windings, each of the sets of transformer windings including a plurality of windings connected to a common connecting point, the two common connecting points being connected together by means of an inductive winding which either constitutes, or is a part of, an interphase transformer.
(1) Note. One of the more common types of transformer means included in the subclasses is the type wherein the secondary of the transformer is provided with two star connected polyphase windings, the neutral points being connected together by means of an inductance, the star connected windings being connected to either (1) a plurality of discharge devices or (2) to the anodes of a plural cathode and/or anode discharge device, the common return conductor from the plural discharge devices or the return conductor from the cathode of the plural cathode and/or anode discharge device being connected to the midpoint of the inductance so that the inductance functions as an interphase autotransformer.
