Abstract
An arrangement for measuring alternating or direct current based on the magnetic field generated by the flow of the current includes a sensor for sensing the magnetic field generated by the flow of the current, a measuring circuit for determining the current from the magnetic field, and a device for sensing an external parasitic magnetic field and producing a correction signal applied to the measuring circuit for accurate measurement of the current.
