Abstract
A system and method for current sensing includes a conductor configured to receive current flow therethrough and generate magnetic flux thereabout. The current sensor system also includes an anti-differential current sensor configured to monitor magnetic flux about the conductor and a flux concentrator configured to concentrate magnetic flux induced by current flow through the conductor.
