Abstract: To each selected section, two compensation loops (1,7) are provided covering the phase conductors in the form of a roof. Each consists of a horizontal upper conductor(2,8) located above the upper phase conductor, a horizontal lower conductor (3,9) found laterally below the lower phase conductor and two side connecting conductors (4,5). The overhead line has three phase conductors located one above the other. The phase conductors are embraced along at least one selected section by compensation loops. The phase positions and amplitudes of the compensation currents generated in the loops by a driving voltage are designed so that the magnetic and electric fields generated work against those of the phase currents.
