| 摘要 |
The present invention relates to an arrangement for reduction of magnetic alternating fields for example in a vehicle or similar which comprises at least one electrical system which comprises at least two arrangements (4, 5) of which at least one comprises one or more components generating and/or consuming electricity, and which are connected through at least one connecting cable or a disturbing cable (1) in which flows a current (IB) having an alternating current component generating a low frequency magnetic field. The arrangement also comprises at least one detecting arrangement (7) which is arranged to detect the current, at least the alternating current component, and means (6) for generating a compensating current (IC) with the use thereof, which compensating current (IC) flows adjacent to the cable (1) which contains the alternating current component giving rise to the low frequency magnetic field in such a way that the disturbing magnetic field is reduced or eliminated.
