This model was presented in.

3 phase electric arc furnace.

The metter is a sealed 1 t 1 1 st three phase 800 kv a electric arc melting furnace with lo 2 cm 4 in diam eter graphite electrodes water cooled roof and sidewalls and four water cooled feed tubes. The electric arc furnace is a nonlinear and unbalanced high power three phase charge. The three phase electrical input serves as the main energy input in the electric arc furnace. A water cooled copper f1x1 ure provides for continuous tapping of slag.

In are presented models of electric arc from which the authors used in their simulations the model based on formulas that relate arc radius length the arc voltage and the current. Each phase of the three phase electrical input supplies power to one of the three electrodes that is mounted above the furnace bath through the roof. One example of a three phase load is the electric arc furnace used in steelmaking and in refining of ores. A 3 phase electric arc furnace has the following data.

The furnace roof is closed when power is supplied to the system. Current drawn 9000 a transformer resistance referred to the secondary 0 003 s2 transformer reactance referred to the secondary 0 0052 overall efficiency 65 the charge steel has the following data. A 3 000 degree fahrenheit electric arc furnace prepares to receive a charge of scrap metal for conversion into steel saturday at severstal columbus photo by carmen k. The electrical energy input needs to be controlled with the aim of achieving the lowest possible production cost.

In many european countries electric stoves are usually designed for a three phase feed.
