摘要：The invention relates to a device for the contactless determination of theenergy requirements of a point actuating drive (7), comprising asynchronous motorswhich are connected to a three-phase current source (1) via conductors. According to theinvention, at least one inductance coil is mounted in parallel to a phase conductor and theconductor that is connected to the inductance coil is guided in the opposite direction ator through a sensor (5), wherein the blind current component produced in the throttle(4) compensates at least partially the blind current component that is, in addition to theeffective power component, contained in the line which is guided via the motor winding.
