Abstract
Improved current sensing methods and apparatus and conductor apparatus are presented for sensing current in a bus bar or other conductor using one or more circular magnetic sensors or multiple magnetic sensors disposed on a substrate in a pattern surrounding a longitudinal path within the outer periphery of the conductor to avoid or mitigate sensed magnetic field crosstalk and to facilitate use of high sensitivity magnetic sensors at locations inside the conductor periphery in which the magnetic field is relatively small.
