Abstract
A current sensor includes a current sense coil disposed about a conductive lead, the current sense coil configured to sense a current passing through the conductive lead. The current sense coil includes: a first outer coil configured to detect a first magnetic field generated by the current; a second outer coil configured to detect the first magnetic field, the second outer coil further configured to cancel an electrical field induced in the first outer coil; and an inner conductor disposed between the first outer coil and the second outer coil, the inner conductor configured to detect a second magnetic field generated by the current.
