Abstract
A voltage and current sensor comprised of a plurality of surface mounted inductors serially connected around the circumference of a current carrying conductor and a plurality of surface mounted resistors each connected in parallel with an inductor wherein an electrical circuit connected to the inductors and resistors provide a measurement of current in the conductor. The inductors and resistors are mounted on a printed circuit board that has a plated aperture for receiving the current carrying conductor there through. An electrical circuit connected to the plated aperture provides a voltage measurement.
Claims4
