ABSTRACT:
An alternating current sensor includes a conductive pipe and a cylindrical-shaped conductive element preferably partially surrounded by the pipe. The pipe is substantially concentric to the conductive element and a conductor electrically connects a pair of corresponding ends of the pipe and conductive element to form a connected conductive path through the sensor. The pipe and the conductive element are spaced apart a predetermined radial distance to form a magnetic field in the space between the pipe and the conductive element during current flow along the connected conductive path. A flux sensor, such as an air-core coil, senses changes in magnetic flux over a sense region situated in the space between the pipe and the conductive element. A transformer having a saturable magnetic core is responsive to a magnetic field over a transformer region for generating a predetermined level of electrical current which can be used for safely powering various electrical circuits associated with the current sensor.
