摘要： The invention relates to a current transformer comprising a primary conductor, a secondary winding and a soft-magnetic core, whereby the primary conductor and secondary winding are electrically insulated from one another and are magnetically intercoupled via the core. In addition, a current to be detected is injected into the primary conductor, and a compensating current is injected into the secondary winding. According to the invention, an additional conductor is provided which is electrically connected in parallel to the primary winding, and which is situated in the area of the core at which a flux rise occurs, whereby the flux rise is at least partially compensated for by the flux elicited by the current flowing in the additional conductor.

摘要： The invention relates to an arrangement comprising a current sensor, containing a bypass-branch (3) which is electrically connected in a parallel to a defined section of the current conductor (1) and a current probe (5) for measuring the current in the bypass-branch (3), a fixed dividing ratio for the current passing therethrough existing between the bypass-branch (3) and the bridged section of the current conductor (1). The dividing ratio and the electric resistance of the bypass-branch (3) are relatively high in comparison to the resistance of the bridged section of the current conductor (1), whereby the contact resistances (Rk) between the current conductor (1) and the bypass-branch (3) are negligible in relation to the resistance (RBY) of the bypass-branch (3).

摘要： A conductor (111) is guided through a toroidal core (110) so that conductor and toroidal core form an inductive arrangement (11). An evaluation circuit (12) is adapted to evaluate the saturation state of toroidal core of inductive arrangement as a measure of the distance of transmitter magnet (10) relative to the magnetic core. Magnetic core is designed as a toroidal core formed of amorphous or nanocrystalline films having maximum thicknesses of 30 micrometers and relative permeabilities of at least 20,000.

摘要： A measuring method for measuring currents with a large dynamic range by means of a magnetic measuring module has the steps of switching into a high-current mode when a current threshold value is exceeded, and switching into a low-current mode otherwise, wherein the low-current mode has the following steps:-Feeding a first current pulse to a compensation coil, which drives a magnetic core in a first direction until magnetic saturation occurs,-measuring a first primary current value I 1 after the current pulse is disconnected,-feeding a second current pulse to the compensation coil, which drives the magnetic core in a counter second direction until magnetic saturation occurs,-measuring a second primary current value I 2 after the second current pulse is disconnected,-determining the corrected primary current value subsequently as an average value I=(I 1 +I 2 )/2 from the first and the second primary current values.
