| description | A low-cost and high-precision current sensing device and methods for use and manufacturing. In one embodiment, the current sensing apparatus comprises a Rogowski-type coil which is manufactured in segments so as to facilitate the manufacturing process. In an exemplary embodiment, the current sensing apparatus segments are asymmetric in shape and/or composition (e.g., bobbin shape, size, and/or winding configuration) so as to account for asymmetries in the magnetic field distribution around a bus bar, or to accommodate its shape in a more compact form factor, and/or to improve the immunity to the effects of an external magnetic field. Methods of manufacturing and using the aforementioned current sensing apparatus are also disclosed. |
