Devices for sensing current

摘要

Devices for sensing current are described herein. One device includes a first magnetic sensor configured to determine a first magnetic field associated with a current conductor while the current conductor is conducting a current, a second magnetic sensor, a particular distance from the first magnetic sensor, configured to determine a second magnetic field associated with the current conductor while the current conductor is conducting the current, and a fastener configured to secure the current sensor to the current conductor such that the first and second magnetic sensors are on a plane substantially perpendicular to a longitudinal axis of the current conductor.

1. A current sensor, comprising:
a first magnetic sensor mounted on a first face of a circuit board and configured to determine a first magnetic field associated with a current conductor while the current conductor is conducting a current; a second magnetic sensor mounted on the first face of the circuit board and configured to determine a second magnetic field associated with the current conductor while the current conductor is conducting the current, wherein the circuit board curves around the first magnetic sensor and the second magnetic sensor such that the first magnetic sensor abuts the second magnetic current sensor; and a fastener configured to secure the current sensor to the current conductor such that each magnetic sensor of the current sensor is on a single radial line extending outward from a point on or within the current conductor, and the first magnetic sensor is disposed between the second magnetic sensor and the current conductor.
