Abstract
Embodiments of the present disclosure provide mechanisms for measuring currents flowing in one or more conductor wires. The mechanisms are based on using magnetic sensor pairs arranged within a housing with an opening for the wires, where each magnetic sensor pair can generate a pair of signals indicative of magnetic fields in two different directions. The outputs of the sensor pairs can be used to derive a measure of current(s) flowing through the one or more wires. The use of magnetic sensor pairs that can measure magnetic field in two different directions may enable simultaneous current measurement in multiple wires placed within the opening, improve accuracy of current measurements while relaxing requirements for precise control of the placement of the wire(s), reduce the impact of stray magnetic interference, and enable both AC and DC measurements.
