Experimental Studies of Systems of Active Shielding of the Magnetic Field With an Orthogonal System of Compensation Windings

A physical model of single-circuit three-phase power line with a horizontal arrangement of wires and systems of active shielding of magnetic field with a system of six orthogonally arranged square Helmholtz shielding windings have been developed and manufactured. Experimental research of open, closed and feed forward systems of active screening of the magnetic field with a system of six orthogonally arranged square Helmholtz windings were carried out. The possibility of reducing the level of magnetic field induction in a given zone by a factor of 5–10 for a system of active shielding of a magnetic field with a system of six orthogonally arranged square Helmholtz shielding windings of a magnetic actuator has been experimentally confirmed. The possibility of reducing the level of magnetic field induction in a limited area of the considered space by 15–50 times is shown.
