Calculation of arc-circuit asymmetry in electric-arc furnaces [PDF]

IEE Proceedings B Electric Power Applications, 1983
A method is described to determine the arc voltages on a per-phase basis of a 3-phase direct electricarc furnace. Having determined the arc voltages, other arc parameters, such as arc resistance, length and power, can then be obtained. By using the procedure outlined, in conjunction with experimental data on a 100 t, 5½m diameter shell furnace having ...
