Abstract
A system and method for measuring current flow through a conductor. The system includes a core having a general ring shape and a central opening. The core terminates at two ends that form a gap for receiving a Hall generator. The core is electrically coupled to a ground to prevent electrical noise on the conductor from being coupled to the Hall generator, thus permitting the direct use of the voltage signal output by the Hall generator.
