3 Phase Electric Arc Furnace

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

3 phase electric arc furnace.

The electric arc furnace is a nonlinear and unbalanced high power three phase charge. The furnace roof is closed when power is supplied to the system. 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. 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.

A 3 phase electric arc furnace has the following data. The three phase electrical input serves as the main energy input in the electric arc furnace. The electrical energy input needs to be controlled with the aim of achieving the lowest possible production cost.

Individual heating units are often connected between phase and neutral to allow for connection to a single phase circuit if three phase is not available.
