Ferrite method and device particularly for thermocouples and other dissimilar metal conductor combinations

Abstract

The invention relates to electrical devices which include at least one pair of dissimilar metal members with respective surfaces for bringing into contact with each other or with other receptors to establish an electrical connection, and antenna-effect inhibiting means such as a ferrite composition are disposed adjacent to the connection surface of at least one of the contact members. In a form of the invention for use with single wires or a pair of multiple wires, each wire is provided with an individual antenna-effect inhibiting means, such as a ferrite housing, adjacent to a connector thereon. The invention also provides a method of making an electrical connector, having at least two electrical conduction elements of dissimilar metals, which includes steps of forming at least two dissimilar metal conductors to engage corresponding metal conductors at a junction, providing a ferrite element mounted in proximity to at least one connector near said junction and providing means to measure and display the current passing said junction. In a further method in accordance with the invention, operating an electrical circuit comprises providing at least two conductors of dissimilar metals, providing a ferrite element near at least one of those conductors of dissimilar metals at a junction with a conductor of the metal, passing an electric current through the at least two conductors, and measuring that current.
