Current sensing using panel plane

Abstract

An apparatus for sensing current on a conductor of an electrical panel includes at least one sensing system, which comprises a ferromagnetic body and a sensor. The body can be formed of a ferro-magnetic material, such as for example steel. The ferromagnetic body can have two legs, which when placed on a load-side of the electrical panel, is configured to form, together with a back plane of the electrical panel, a magnetic path around the conductor. The ferromagnetic body comprises at least two parts with a first air gap therebetween along the magnetic path. The sensor, which is arranged in the first air gap, is configured to measure a current or other electrical property representative of current on the conductor based on the magnetic field across the first air gap.
