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.

Abstract: An overhead power line has at least one additional compensation loop. At least one conductor (7) of this/these loop(s) is parallel to, and near, the phase conductor nearest the ground and into this/these loop(s) is fed a compensation current whose phase and amplitude are adjusted relative to the phase angles and amplitudes in the three phase conductors so that its magnetic field works against that of the phase conductors. The compensation current is generated from a power supply (3) with a controller (5) connected with a magnetic field sensor (6). The compensation loop(s) has/have a series condenser(4). For a three phase system stacked one conductor above another, one conductor of the compensation loop(s) is above the uppermost phase conductor and the other is below the lowest phase conductor.
