ABSTRACT:
A noninductive shunt current sensor includes a cylindrical-shaped conductive element and a concentric conductive pipe electrically connected at one end by a conductor, such as a washer. Except for the conductor, the pipe and conductive element are electrically isolated from each other by insulation, such as a polyimide or an air-gap. Sensing wires are electrically connected to contact points, each contact point being located on either the inner surface of the inner pipe or the outer surface of the outer pipe. The wires pass through a space where the magnetic field is substantially null, thereby minimizing any mutual coupling effects. A magnetic core and a coil can be situated between the pipe and the conductive element to provide an electrical self-power capability to the noninductive shunt current sensor.
