Why do we need to transpose the cable in power system?

Question

The question above relates with the Transpose Line.One of the subtopics under Transmission Line Parameters in Power System.

Answer 1

If the adjacent line induces current in a nearby cable that would be a problem. Transposing results in one section having an induced current with a certain phase but the next section (after the transposition) has an induced current with the opposite phase. Over the length off the cable, the opposing induced currents will cancel each other out.
