A precision printed circuit board based Rogowski coil is formed including a printed circuit board including a first layer and second layer. The printed circuit board further defines an aperture for receiving an electrical path therethough. A first return path is defined about the aperture on the first layer of the printed circuit board, and a second return path—parallel to the first return path—is defined about the aperture on the second layer of the printed circuit board. A plurality of radial paths defined on the first layer of printed circuit board extend between the aperture and the first return path. A plurality of radial paths defined on the second layer of the printed circuit board extend between the aperture and the second return path. Each first layer radial path is connected with an adjacent second layer radial path to form a generally toroidally-shaped winding.
