A Busbar Current Sensor With Frequency Compensation
DC/AC yokeless galvanically insulated electric current sensors are required for applications, e.g., in automotive and aerospace engineering, where size, weight, and/or price are strictly limited. A busbar current sensor ...
Contribution to the Ring-Core Fluxgate Theory
(The Royal Swedisch Academy of Sciences, 1989)
Existing theories for open-core fluxgate are not fitting experimental results in the case of ring-core sensors. Simple description based on transfer functions which takes into account the interaction between two half-cores ...
Three-Phase Busbar Current Transducer
A true three-phase 1000 A busbar current transducer is based on six micro-fluxgate sensors. Instead of using three independent single-phase current transducers, we use the full information from each sensor. Two TI DRV425 ...
AC/DC Current Transformer With Single Winding
AC/DC Current Transformer With Single Winding is a device which allows simultaneously measure AC and DC current using fluxgate effect
A 3-Phase Current Transducer based on microfluxgate sensors
Novel 3-phase DC/AC current transducer for 3-phase current lines is based on 8 integrated fluxgate sensors. Using full information from each sensor rather than gradiometric pairs, we suppress crosstalk between individual ...
Flugate Sensor With Pulse Feedback
Fluxgate sensors have typically only 100 μT range, which sometimes limits their applications. The main obstacle for increasing the measurement range is the power dissipated in their feedback coil. Until now, the feedback ...
Effect of Stress Induced Anisotropy on the Noise of Ring-core Fluxgate
In this paper we show how an anisotropy perpendicular to the direction of excitation is favourable to obtain low noise in fluxgate sensors. We produced ring cores by electroplating NiFe thin film (6 μm) over a bended copper ...
Fluxgate Offset Study
Offset and its long-term stability is a weak point of fluxgate sensors. Even the ultrastable sensors kept at no vibrations and stable temperature at magnetic observatories show offset drift. Such drift of the fluxgate ...
Multiwire Core Fluxgate
(Elsevier Science, 2009)
Multiwire core fluxgate has higher sensitivity due to the higher cross=sectional area of the core
Effect of Electroplated Ni1-xFex Composition on the Field-Induced Anisotropy
Field-induced anisotropy has been proposed as an effective method to produce ferromagnetic rings with radial anisotropy for fluxgate cores. Compared with stress-induced anisotropy, this method easily allows generating a ...
