Abstract
A current measurement device with a shunt resistor of a resistive core with an opening and measurement leads, a Rogowski coil with electrical contacts surrounding the resistive core, conductive layers on first and second sides of the resistive core, one or more insulative layers between the conductive layers and the Rogowski coil, the current measurement device configured to combine signals from the shunt resistor and the Rogowski coil. The current measurement device may have a Rogowski coil on a flexible substrate at least partially wrapped around the shunt. A current measurement device has a rigid substrate, vias filled with a conductive material through the rigid substrate, conductive layers on the top surface and the bottom surface connecting to the vias to form a Rogowski coil structure, one or more insulative layers directly on the coil structure, a shunt resistor directly on the one or more insulative layers.
