Abstract
Shielded Rogowski coil systems having separate interface cables and methods for eliminating and monitoring noise in signal transmissions over the cables. An embodiment of a Rogowksi coil system includes a first Rogowski coil surrounding a conductor and generating a first voltage output signal, and a second Rogowski coil surrounding the conductor and generating a second voltage signal, wherein the first voltage output signal and the second voltage output signal are processed to address noise components in the output signals. An exemplary method of eliminating and monitoring current with a Rogowski coil includes providing first and second Rogowski coils, connecting an interface conductor to each coil, obtaining distinct voltage outputs from each coil, and applying a noise effect algorithm to the voltage outputs.
