Abstract
An exemplary embodiment provides a current sensor comprising a printed circuit board (PCB), a Rogowski coil, and a controller. The PCB can comprise an aperture configured to receive a conductor carrying an alternating electrical current. The Rogowski coil can be positioned on the PCB along a perimeter of the aperture. The controller can be in electrical communication with the Rogowski coil and configured to generate an output signal indicative of the alternating electric current carried by the conductor. The current sensor can be configured to measure the alternating electric current relative to a full scale at a resolution of 1000:1 and at an accuracy within 1%, wherein the full scale can range over 5000:1.
