    Abstract: A system for a machine, in particular an automated production machine, has a large number of proximity sensors. Each proximity sensor has at least one secondary winding that is suitable for drawing power from a medium-frequency magnetic field. At least one primary winding, which is fed from a medium-frequency oscillator, is provided for supplying the proximity sensors with electrical power without using wires. Each proximity sensor is equipped with a transmitting device that emits radio signals, which contain sensor information of interest, to a central receiving device that is connected to a process computer for the machine. A proximity sensor and a primary winding for this purpose are also proposed.

    Abstract: The power line has an additional, compensation, loop (1) surrounding at least one phase conductor. Into this compensation loop a compensation current is fed via a driving voltage. This current's phase angle and amplitude are adjusted relative to the phase conductor current angles and amplitudes so that its magnetic field works in opposition to that of the phase conductors. The driving voltage in the compensation loop and in at least one additional loop, which also surrounds a phase conductor and is connected with the original loop, is generated so that the overhead line is divided into at least two main sections. One section is with the original loop and one is with the additional loop.
