A Study on the Electrode Protection System of an 100t Ultra High Power   Electric Furnace
  In this paper a method to design the electrode protection system using arc current and voltage and pressure inside the hydraulic cylinder of electrode lift device of an 100t ultra high power furnace (UHP furnace) and confident factor(CF) and Lyapnov function, and then we validated our method through the field experimentation.
