Abstract
A self-powered axial current sensor for generating a signal which accurately represents current in a power line includes, in one embodiment, a housing having a bus bar opening of substantially rectangular shape extending longitudinally therethrough. The housing also includes current sensor core retaining walls which define a current sensor region, and a cover base wall which defines, with one of the retaining walls, a power core region. A current sensor core and coil are located in the current sensor region and are positioned proximate the bus bar opening. The current sensor core and coil also are substantially symmetrical with respect to the center axis of the bus bar opening. The current sensor further includes a power core and a power coil located in the power core region and positioned substantially symmetrically with respect to the center axis of bus bar opening.
