Abstract: A current measurement device includes a shunt having sense leads, the shunt configured to be located in a current path for a current to be measured, and a Rogowski coil at least partially wrapped around the shunt, the current measuring device configured to combine signals from the shunt and the Rogowski coil. A current measurement device includes a shunt having sense leads configured to be located in a current path for a current to be measured, a Rogowski coil in series with the sense leads and at least partially wrapped around the shunt, a compensating pole connected to the Rogowski coil, and an isolation barrier connected to the compensating pole.

Abstract: A current sensor configured to measure current in a current-carrying conductor. The current sensor includes a shunt configured to be placed in series with the current-carrying conductor, and a Rogowski coil including at least one conductor segment. The shunt and the Rogowski coil are coupled to produce an output signal representing the current in the current-carrying conductor.
