Abstract
Power lines include three or more conductors for transmitting alternating currents. The conductors are arranged in one combination of the conductor arrangement so that the sum of phase differences between the currents flowing through adjacent conductors is maximum, and if there exists a plurality of such combinations, the one combination is selected in which the value of the smallest one of the phase differences between the currents flowing through every adjacent conductor is largest. With this arrangement, power loss is reduced.
