摘要： A transducer for measuring a current, includes a magnetic core which has a gap substantially impeding passage of any magnetic flux, a coil arranged to pass a premagnetizing current for producing a first magnetic field, a loop for carrying the current to be measured, so as to produce a second magnetic field, and a magnetic field comparision device exposed to the magnetic fields. The magnetic field comparison device includes a magnetic film bridging the flux gap. The film is alternately controllable in respective opposite directions of saturation substantially by the first magnetic field, and evaluates the measuring current in dependence of the magnetic fields. The magnetic core, the coil, the loop, and the magnetic film are substantially disposed concentrically.

摘要： A phase detector includes a pulse amplitude modulator and an integrator. The pulse amplitude modulator comprises a change-over switch the control input of which is fed by pulses which are subjected to mark/space modulation by means of a phase-shifted signal while the amplitude input of the pulse amplitude modulator is fed by a non-phase-shifted signal. The integrator includes an integrating amplifier, the output of which is connected by means of a capacitor to an inverting input of the integrating amplifier while the non-inverting input of the integrating amplifier is connected to ground by way of a further capacitor. The inverting and non-inverting inputs of the integrating amplifier are connected by way of respective resistors to two inputs of the integrator which in turn are connected to ground by way of respective resistors on the one hand and which on the other hand are connected by way of respective switch contacts of the change-over switch to the amplitude input of the pulse amplitude modulator. The phase detector requires only a single amplifier and may be used in phase-lock loops of static electricity meters which operate using the mark/space amplitude modulation method and which serve for the measurement of reactive energy, and which therefore require a 90.degree. phase shift provided by the phase-lock loop.

摘要： A precision measurement voltage transducer is fed from a reference alternating current source and comprises a transformer and a servo amplifier. The transformer comprises a feedback winding, a magnetizing winding and an output winding. The feedback winding and the magnetizing winding together with the servo amplifier form a feedback control regulating system, which adjusts the input voltage of the servo amplifier to zero. The latter comprises two amplifiers, which according to a first embodiment are connected in series and which according to a second embodiment feed the two poles of the primary winding of a second transformer, the secondary winding of which forms the output of the servo amplifier. According to the first embodiment the second amplifier is provided with a positive and an equally strong negative feedback and according to the second embodiment the transfer ratio of the second transformer equals the amplification factor of the second amplifier.

摘要： A measuring transformer comprises a ferromagnetic core having a central branch. The central branch comprises at least one unit that is surrounded in part by an electrical conductor in the form of a U. Each unit of the central branch of the core has two outer air gaps and one or more central air gaps. Each outer air gap has length, that when measured in the longitudinal direction of the unit, is longer than the sum of the lengths of the one or more central air gaps. At least one magnetic sensor is contained in a central air gap of each unit and the central branch includes a total of at least two magnetic sensors. The measuring transformer is especially well suited for use in multifunction measuring instruments.

摘要： An apparatus for determining the reactive energy of a circuit includes a mark-space modulator, which has an input terminal normally accepting a first signal input, and an output terminal, a pulse amplitude modulator which has a bipolar modulating terminal normally accepting a second and bipolar signal input, a signal output terminal, and a pulse input terminal, and a delay circuit which has a data input terminal connected to the output terminal of the mark space modulator, and which has an output terminal connected to the pulse input terminal of the pulse amplitude modulator. A predetermined phase angle at an operating frequency of the delay circuit normally occurs between the input terminal and the output terminal of the delay circuit. A regulator is interconnected between the mark-space modulator and the delay circuit so as to maintain the phase angle at the operative frequency as close as possible to 90 degrees, even when the signal input is subject to any level variations or to any interference.

摘要： The current transformer for instruments for measuring electric currents includes a magnetic core that has two cores and an inductive current divider with three parallel current paths. The current dividers form, together with cores, two current transformer stages whose magnetic fluxes mutually cancel one another. In a current transformer for AC currents having a DC component, the ratio of the ohmic resistances of the individual current paths is in direct relation to their transformation ratio.
