Abstract (en)

[origin: WO2016075404A1] A line protection electromagnetic actuator, comprising a differential winding (2) generating a magnetic field in response to a differential fault on the current line to be protected, and a magnetic winding (1). This electromagnetic actuator is characterised in that it also comprises a third winding (3) engaged with said differential winding (2) and magnetic winding (1), traversed by a current of which the direction is reversed relative to that of the differential winding (2) when a current flows between the phase Ph and the neutral N of the actuator, and generating a magnetic field opposed to the magnetic field created by the differential winding (2), said third winding (3) being connected in parallel to the differential winding (2), between the phase Ph and the neutral N of the line to be protected, and controlled by control means.
