Abstract
Device for controlling the load of the contact plates of the arc furnaces or of all the conductors in parallel traveled by an alternating current, which essentially comprises the association, at each introduction of current in said plates or in said conductors, of a transformer constituted by a coil in whose terminals the voltage grows decreases with the intensity of the current that crosses the plate the conductor, and that feeds a signaling lamp, allowing a switch to also put in contact each transformer with a voltmeter of measurement of said intensity.
