Abstract: Systems and methods for measuring currents in bundled conductors. A frame holding a number of sensors is used. The geometric and electrical parameters of the sensors in the frame are known or previously determined. The frame is then deployed to substantially encircle at least part of the bundled conductors. The magnetic fields produced by the current in the bundled conductors are then sensed by the sensors. The sensed magnetic fields are then turned into relevant data. The relevant data, in conjunction with the geometric and electrical properties of the sensors are then used to calculate and estimate the current in each of the bundled conductors. The parameters of the sensors may be determined during the assembly or manufacture of the frame and the sensors.

Abstract: Disclosed is a current sensor (600) that senses current flow in a conductor (604) by coupling a first magnetic field generated by the conductor to a sense element (602). The current sensor includes a shield (700) including a first material (702a,702b) that sandwiches the sense element to define a stack and a second material (704a,704b) that sandwiches the stack. The shield is configured to generate a second magnetic field, responsive to a third magnetic field external to the current sensor that opposes the third magnetic field. The shield is further configured to prevent production of a magnetic field that opposes the first magnetic field generated by the flow of current in the conductor.

Abstract: A sensor comprises primary ferrite members (362) spaced apart from the magnetic field sensor (20) on opposite sides of the magnetic field sensor to concentrate or steer an orientation of a magnetic field of the observed signal toward a target area (409) of the magnetic field sensor (20). A magnetic field sensor (20) senses a direct current signal component or lower frequency component of the observed signal. A first filtering circuit has a high-pass filter response. The first filtering circuit is coupled to the inductor to provide a filtered alternating current signal component. A second filtering circuit has a low-pass filter response. The second filtering circuit coupled to the magnetic field sensor to provide a filtered direct current signal component. A sensor fusion circuit determines an aggregate sensed current based on the filtered alternating current signal component and the filtered direct current signal component.
