Abstract

The invention relates to a device for the contactless determination of the energy requirements of a point actuating drive (7), comprising asynchronous motors which are connected to a three-phase current source (1) via conductors. According to the invention, at least one inductance coil is mounted in parallel to a phase conductor and the conductor that is connected to the inductance coil is guided in the opposite direction at or 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 the effective power component, contained in the line which is guided via the motor winding.
