Abstract
Abstract: Electrical arc is a stochastic process; witch is the principal cause of power quality problems, including
voltages dips, harmonic distortion, unbalance loads and flicker. So it is difficult to make an appropriate model for an
EAF. The factors that effect EAF operation are the melting or refining materials, melting stage, electrode position (arc
length), electrode arm control and short circuit power of the feeder
So arc voltages, current and power are defined as a nonlinear function of the arc length. In this article we propose our
own empirical function of the EAF and model for the mean stages of the melting process. This study is important,
because improvement of Electric Arc means high productivity (in tons/year) and lowest possible costs arising form
energy consumption, electrode and refractory wear.
