    Abstract: A magnetic current sensor calibration system includes a plurality of sensors and a substrate. The substrate has a first surface and a second surface, and the sensors are mounted on the first surface. The substrate includes a bipolar calibration conductor and a unipolar calibration conductor. The bipolar calibration conductor is spaced apart from the plurality of sensors and is disposed between the first and second surfaces. The unipolar calibration conductor is spaced apart from the plurality of sensors and the bipolar calibration conductor, and is disposed between the first and second surfaces.

    Abstract: Apparatus and associated methods relate to an in-hole current-measurement system having three or more magnetic-field sensors and a transient-disturbance selection module configured to form an output signal from a selected subset of sensor signals while decoupling the output signals from a non-selected subset of sensor signals during a predetermined time window when a disturbance signal is expected at the non-selected set of sensor signals. In an illustrative example, a disturbance producing operation may be performed on alternating subsets of sensors while the undisturbed subset of sensors measures an electrical current in the electrical conductor. For example, each selected subset of sensors may be aligned on an axis configured to be mounted perpendicular to current flow within a hole in the electrical conductor. Some embodiments may advantageously provide continuous electrical current measurement while being uninterrupted by the predetermined transient disturbances.
