US Patent No: 9791477
Plug-through energy monitor
Abstract
A sensor for inductively measuring the current in a conductor flowing through a recess in a printed circuit board. Wire loops on the printed circuit board function as the inductive current sensor. Combined with a voltage measurement, the energy being dissipated in the conductor's load circuit can be determined and transmitted wirelessly. Control circuits can be integrated with the metering hardware to enable the remote modulation of the load's power. The inductive sensor(s) can be used to track differences between the load's supply and return currents. If a fault is detected, the circuit can be broken for safety, serving a ground fault circuit interruption (GFCI) purpose.
