Description
Technical field [0001] The invention relates to the field of electrical conductivity measurement of electrical materials, in particular to a device and system for measuring electrical conductivity of strip-shaped electrical materials at different temperatures. Background technique [0002] In the field of electrical engineering, the electrical parameters of magnetic materials and related metal alloy materials, such as electrical conductivity, have an extremely important impact on the overall performance of electrical equipment. Electrical parameters can directly affect the copper loss and related core loss. In addition, due to the indivisibility of electromagnetic coupling, the eddy current effect closely related to the conductivity of the material will have a serious impact on the magnetic field environment such as the magnetic material in the device. Changes in these factors will bring about various problems such as temperature rise, heat dissipation and insulation life of the ...
