Abstract
Induction powered electrical current monitoring, and related devices, apparatuses, systems, and methods are disclosed. An electricity current monitoring device can include an inductive energy transfer medium, an energy storage device, a power management circuit, and a processing circuit. The inductive energy transfer medium can induce an electromotive force to produce electrical energy that can be stored in the energy storage device. A power management circuit can control storage of the electrical energy in the energy storage device and can control release of the electrical energy from the energy storage device. The processing circuit can measure the electrical current in the monitored energy source based on the fluctuating magnetic field generated by the inductive energy transfer medium. The processing circuit is electrically coupled to the power management circuit to be powered using the electrical energy released from the energy storage device.
