  • Cross coil meter
    Patent number: 5243277
    Abstract: Disclosed herein is a cross coil having a first coil winding for generating a first magnetic field when an electrical current flows therethrough and a second coil winding for generating a second magnetic field when an electrical current flows therethrough, and the second coil winding being wound so as to cross the first coil winding to each other. The cross coil comprises a mechanism for equalizing the magnitude of each of the first and second magnetic fields generated when identical electrical currents flows through each of the coil windings.The equalizing mechanism comprises the arrangement of the turns of the windings in which the individual turns are alternately wound on top of the turns for the other winding.
    Type: Grant
