Abstract
Systems and methods for sensing current provide a Rogowski coil type current sensor for a current flow monitoring device in which the coil windings are formed by electrically conductive traces on a printed circuit board (PCB) substrate. Each coil winding is composed of two or more elongate traces formed on a PCB substrate and extending radially outward from a central opening or hole in the PCB substrate. Each trace coil winding is connected to electrically conductive vias, one via at each end of the trace. The via at one end connects the trace to another trace in coil winding, while the via at the other end connects the trace to a different trace in the same coil winding or an adjacent coil winding. The result is a conductive helix encircling the central opening in the PCB substrate that electrically resembles a Rogowski coil.
