Electrical current sensing apparatus

摘要

An apparatus (40) for use in sensing electrical current in a conductor (22) includes a flux concentrator (42) and one or more magnetic flux sensors (20). The flux concentrator (42) includes main sections (50 and 52) which are formed of a magnetic material. One or more intermediate sections (54 and 56), formed of a nonmagnetic material, extend between the main sections (50 and 52) of the magnetic flux concentrator (42). The main sections (50 and 52) and intermediate section (54) of the magnetic flux concentrator (42) cooperate to at least define an opening (88) through which a portion of the conductor (22) extends. <IMAGE>
