Abstract
A current sensor arrangement for measuring an AC electrical current, comprising: an electrical conductor having three transverse rectangular cut-outs; a sensor device comprising two sensor elements spaced apart along a first direction for measuring two magnetic field components oriented in said first direction, and configured for determining a magnetic field difference or magnetic field gradient, and for determining the AC current based on said difference or gradient. The sensor device is positioned at a particular location relative to the second cut-out, such that the magnetic field difference or gradient is substantially proportional to the AC current for frequencies from 100 Hz to 2 kHz. A current sensor system. A method of measuring an AC current with improved accuracy.
