ABSTRACT:
A current sensor includes a first conductor plate, a second conductor plate positioned in spaced relationship relative to the first conductor plate and facing the first conductor plate, and a third conductor plate for electrically interconnecting the first and second conductor plates to form a connected conductive path along the first and second conductor plates. The first and second conductor plates are shaped to form respective magnetic field constituents around each of the first and second conductor plates during current flow along the conductive path. A sensing coil, such as one or more air-core coils, is provided for sensing changes in magnetic flux within a predetermined sense region. An individual conductor, such as a rectangular plate or a suitably shaped conductive structure, is further provided for carrying all the current which flows along the conductive path to produce a magnetic field over a conductor region. The sense and conductor regions are preferably nonoverlapping with respect to one another. A transformer, such as a current transformer, is magnetically coupled to the individual conductor to supply a predetermined level of electrical current which can be conveniently employed for electrically powering various circuits associated with the current sensor.
