An exemplary embodiment of the present disclosure provides a current sensor comprising a current input, a current output, a first current path, and a second current path parallel to the first current path, a Rogowski coil current sensor, and a controller. The first current path can comprise a first switch. When the first switch is in a closed position, current can flow along the first current path between the current input and the current output. The second current path can comprise a second switch. When the second switch is in a closed position, current can flow along the second current path between the current input and the current output. At least one of the first current path and the second current path can pass through an aperture of the Rogowski coil. The controller can be configured to control the first and second switches.

Universal AC/DC current sensor and isolator

An exemplary embodiment of the present disclosure provides an energy meter comprising a current sensor and an interchangeable voltage sensor. The current sensor can be configured to measure an electrical current flowing through a conductor. The interchangeable voltage sensor detachably can be connected to the current sensor and configured to measure an electrical voltage carried by the conductor.

Energy meters and energy monitoring systems and methods

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.
