ARRANGEMENT TIL ELEKTRODEREGULERING AF EN LYSBUEOVN

An impedance controller is used for controlling electrode-to-bath spacing in an arc furnace. Measured quantities proportional to the electrode voltage and the electrode current are determined and an actual impedance value is formed from the measured values by means of a divider. The actual impedance...
