Not illustrated. 1917 Excerpt: ...a greater number of circuits and to arrange these circuits so that there is no inductive interaction. Thus, in Fig. 101 the circuit of II will have less inductive reactance than the circuit of I, although it has the same total circular mils area, because it is subdivided. How and why subdivision See the author's Practical Electricity for a discussion of electromagnetic inductance and reactance. t See the authorts Wiring For Light And Power. Fig. 101.--Showing how a conductor may be subdivided. decreases the reactance of a circuit will be evident from a consideration of some of the numerical examples which follow. Note.--Voltage drop in lines, due to inductive reactance, is best diminished by subdividing the copper or by bringing the conductors close together. It is little affected by changing the size of the conductor. 181. The Arrangement of Conductors in Polyphase Circuits f will next be given consideration. The directions for the calculation of polyphase circuit conductors which are given in following articles, hold only with certain arrangements of the circuit conductors. These arrangements are, however, the ones which ordinarily are, or which may be readily adopted. These conditions need not be considered where the circuit in question is short and, in general, they need not be considered in interior wiring circuits. They become of importance, however, with circuits extending possibly for a distance of over a mile. 182. The Two Circuits of a Two-phase Transmission Should Be so Arranged That There Is No Inductive Interaction.+--Ralph Mershon. t Westinghouse Electric & Manufacturing Company publication. Fig. 102.--Arrangement of phase conductors on cross arms. Such an arrangement may be effected by either of the two methods shown respectively in Figs....
