Effect of Electrode Regulation System on Arc Parameters in Furnace Operation

The paper presents the investigations carried out for determining arc parameters in the operation of electric arc furnaces. Electric arc furnace is a non linear load causing random fluctuations in current. The measurements for quantities like arc parameters, power balance distribution in all phases; concept of wild phase is illustrated. Power quality is affected by the erratic operation of arc causing disturbances in plant operation. Histograms provide the useful information about regulation system behavior. The refractory wear is a major issue in furnace operation The arc voltage and power distribution has influence on refractive index. The records on furnace measurement are analyzed.
