Fig. 2,678.—Transposition diagram for two parallel lines consisting of two wires each.
Fig. 2,679.—Transposition diagram for three phase, three wire line, transposing at the vertices of an equilateral triangle. The line is originally balanced and becomes unbalanced on transposing, a procedure which should be resorted to only to prevent mutual induction.
Fig. 2,680.—Transposition diagram of three phase, three wire line, with center arranged in a straight line.
The inductive effect of one line upon another is equal to the algebraic sum of the fluxes due to the different conductors of the first line, considered separately, which link the secondary line.
