<p>A circuitry (1) for reducing the magnetic field from multiphase power lines for high voltage alternating current is disclosed. One phase (R) is split into two branches (R1, R2) forming a closed loop along a line portion (L). The self-reactance of the loop is adjusted for minimal magnetic field generation in the vicinity of the power line by a coupling to a compensation device, in the form of a capacitor (12), in a separate circuit (11), via a transformer (2).</p> |
