The electrode damage prevention method and apparatus are provided. Electrode damage prevention apparatus, and the voltage / current measuring unit for measuring a voltage and current applied to the electric furnace through the electrode, for computing a difference between the error impedance of the pre-set and arc impedance is calculated from the voltage and current measurement based on impedance computing section and, when the vibration of the electrode and the vibration measuring unit for measuring and calculating the impact value from the measured vibration, impact value exceeds the threshold shock value, and correct the critical error impedance previously set, based on the corrected threshold error impedance to the correction unit for correcting an error impedance, based on the corrected error impedance, preventing by including a position control unit for controlling the position of the electrode so as to follow the reference impedance, to pre-detect the situation occurring electrode cutting electrode the cutting can do.
