These core reactions may be Floating the Stobage Battery on the Line 355 understood by a study of the elementary wiring diagrams shown in Figs. 107and 108. For clearness in following through the design and operation of thereverse-current circuit-breaker, the descriptive lettering of the various partsin Figs. 107 and 108 are identical with those of Figs. 105 and 106. In Fig. 107 the reverse-current circuit-breaker is shown closed in thecircuit with its series coil A connected in series with the main circuit. Theshunt coils C and C, oppositely wound, are connected in series with each. Pig. 108.—Reverse Current Circuit-Breaker (Open Position). other and in parallel across the main positive and negative buses. The bat-teries are shown connected in parallel, and in this manner are floated on theline while the generator is supplying current for the load on the line. Thedirection of the current flowing through the circuit is as indicated by thearrows. Now with the generator running and the current passing from samethrough the series coil A and the shunt coils C and C, their respective mag-netic cores B, D and D are thus inductively magnetized by virtue of the coilfields formed by the generator current; the polarities of these cores are as 256 Storage Batteky Manual indicated and are in accordance with the direction of current flowing throughtheir coils. Thus, in the diagram the induced south pole of pole piece E,
