  • Current measuring apparatus and methods
    Patent number: 10788517
    Abstract: Magnetic sensors may be positioned around an opening for a wire to measure the current flowing through the wire. A non-symmetric positioning of the sensors around the target measurement zone can enable an expanded measurement zone compared to conventional current measurement devices. Further, some sensors may be paired such that a hypothetical line connecting the sensors is tangential to the target measurement zone. Other sensors may be paired such that a hypothetical line between the sensors crosses the target measurement zone. The different pairs of the sensors can enable a reduction in the impact of stray field interference on the measurement of the current flowing through the wire.
    Type: Grant
