Abstract
The method for adjusting the impedance of one or more phases of a secondary circuit of an electric furnace, in order to limit the unbalance between the phases themselves comprises the transformer (), a variable impedance secondary circuit for one or more phases (FFF), the rigid and fixed interconnection () for each phase (FFF) connected to the transformer, the flexible cables () connected by means of the proximal end to the fixed interconnection (), the electrode holding arms () connected to the distal end of the flexible cables (), the conductive electrodes () fixed to the respective electrode holding arms (). The rigid and fixed interconnection () of a phase (FFF) comprises at least one turn (), wherein the impedance is either continuously or discreetly variable in order to obtain the desired impedance value.
