1. A Rogowski coil assembly, comprising:
- a printed circuit board;
a plurality of Rogowski coil sections mounted to an external surface of the printed circuit board by one or more respective circuit traces, wherein the circuit traces secure each end of the plurality of Rogowski coil sections preventing the coils sections from unwinding, connect the plurality of Rogowski coil sections, and to form a return current path, wherein the return current path is formed on a surface of the printed circuit board opposite a surface on which the Rogowski coil sections are mounted;
a substantially circular opening within the printed circuit board configured to receive at least one conductor that is monitored by the plurality of Rogowski coil sections; and
a continuous gap in the printed circuit board connecting the opening and an edge of the printed circuit board, wherein a gap diameter of the continuous gap is substantially smaller than an opening diameter of the opening.
