By transposition of conductors, we mean the exchanging of the position of the power conductors at regular intervals along the line so that each conductor occupies the original position of every other conductor over an equal distance. If the spacing is unequal, even though the system operates under balanced condition, voltage drops of different magnitude will be there in the 3 conductors due to unequal inductance in the 3-phase. Also due to unsymmetrical...
