摘要： The invention concerns a measuring transformer for comparing a current flowing through a conductor to a reference current comprising a magnetic circuit formed by a toroidal core, a conductor through which the current to be measured flows and which is enclosed by the toroidal core, a secondary winding arranged on the toroidal core, and a magnetic field measuring element which is arranged in a gap of the toroidal core and which is sensitive to the magnetic field in the gap. In order to be able to reliably detect even high-frequency deviations from a reference value with such a measuring transformer, it is proposed in accordance with the invention that there is provided a reference setting unit for acting on the secondary winding with a reference current. The measuring transformer according to the invention is preferably used for measuring the output current of an inverter for a wind power installation.

摘要： An IC chip for a magnetic impedance (MI) sensor includes an MI element electrode, a switch unit, and a power supply electrode, wherein the MI element electrode is disposed in the neighborhood of a first side face of the IC chip, and the power supply electrode is disposed in the neighborhood of a second side face opposite the first side face. A power supply voltage is provided to the switch unit through the power supply electrode, and a high frequency pulse exciting current is provided to the MI element through the MI element electrode. Since the first power supply electrode and the MI element electrode are disposed at a distance, noise generated by the high frequency pulse exciting current is prevented from superposing the signals of circuits other than the switch unit.

摘要： A sensor circuit includes a sensor element, a current source for supplying an operating current for the sensor element and an amplifier circuit for amplifying a sensor voltage produced by the sensor element when applying the operating current, wherein the amplifier circuit has a resistor influencing the amplification of it. The resistor of the amplifier current and the sensor element are formed equally as regards technology so that variations, due to technology, of the sensor sensitivity of the sensor element are counteracted by an amplification factor of the amplifier circuit changing in the opposite way.
