Abstract: The three-phase overhead cable has return conductors (7-9) beneath each of the three phase conductors (L1-L3) for connection of components (1-3) of the source, e.g. transformer windings or generators, and/or components (4-6) of the sink, e.g. transformer windings or loads. Counter currents flowing in the return conductors have the same amplitude as, but opposite phase to, the phase currents flowing in the corresp. phase cables.

Abstract: The power line has an additional, compensation, loop (1) surrounding at least one phase conductor. Into this compensation loop a compensation current is fed via a driving voltage. This current's phase angle and amplitude are adjusted relative to the phase conductor current angles and amplitudes so that its magnetic field works in opposition to that of the phase conductors. The driving voltage in the compensation loop and in at least one additional loop, which also surrounds a phase conductor and is connected with the original loop, is generated so that the overhead line is divided into at least two main sections. One section is with the original loop and one is with the additional loop.
