ABSTRACT:
A differential transformer includes a magnetic core within which difference signal detection inaccuracies resulting from non-homogeneity within the core are corrected by compensation. A phase wire extends proximate the magnetic core for transporting a first current in a first direction. A neutral wire extends proximate the magnetic core center for transporting a second current in a second direction which is substantially opposite the first direction. A shunt wire is electrically connected to one of: the phase wire and the neutral wire depending on whether the transformer is undersensitive or oversensitive. The shunt wire shunts a portion of the current flowing in one of the phase and neutral wires such that first and second signals are generated in the transformer as a result of said first and second currents that are substantially equal.
