Abstract：In order to optimize the process and reduce the energy consumption，the measurement and control technology of electro-thermal furnace with AC arc is needed to be improved. A new method for the application of the constant component of phase voltage in Russia is reported.The calculation principle and measurement technology of the constant component of phase voltage and its application in the electric corundum，calcium carbide，phosphorus and LF ladle refining furnace were described. It is hoped that this method can be applied in electro-thermal furnaces like the submerged arc furnace for ferroalloy production and the LF ladle refining furnace to improve the level of measurement and control of the electro-thermal furnaces in China.
