Electronic devices which are installed in the vicinity of heavy-current installations are influenced electromagnetically by such systems. In order to reduce the electromagnetic influence, it is proposed to arrange a compensation conductor (2.1, 2.2) inside a single-phase metal-encapsulated alternating-current system, which compensation conductor (2.1, 2.2) is connected at the start (A) and end (E) of the system, with the aid of short-circuit conductors (K), to the metal jacket (1) of the alternating-current system, as a result of which a compensation loop is produced. An opposingly-directed electromagnetic field, which operates in a compensating manner, is produced around a phase conductor (P1, P2) by coupling the compensation loop to the alternating field in the form of a transformer. <IMAGE>
