Abstract
A current sensor is provided for measuring DC current in a primary conductor also carrying AC current. The current sensor includes a ferromagnetic core through which the primary conductor may extend. The core has a narrow air gap formed therein and a magnetic flux sensor is disposed in the air gap. A secondary winding is mounted to the core and has an impedance connected therein. The impedance has a value of substantially zero at one or more frequencies of the AC current. The impedance may be a short or an impedance source that includes a capacitor and an inductor.
