摘要： Multifrequency equipment is provided for sensing the state of self baking electrodes in an electric arc furnace to obtain real values of the internal situation of an electrode where changes of phase are being produced. By means of said external equipment a small low power and variable frequency electric signal is introduced through a good conducting core component of the electrode and which on changing the frequency of said electric current, will allow the electrode situation to be known at different heights, even beneath the baked plates.
