Electric Arc Furnaces (EAFs), widely used for steel production industries, are highly nonlinear time-variant disturbing loads because of the random change of the electric arc length results in arc voltage and furnace/supply current fluctuations. Consequently, Power Quality (PQ) problems such as undesirable variations of reactive power, poor power factor, harmonics, and voltage flickers may appe...

Wear and corrosion has always had an adverse effect on the performance and service life of electrical arc furnaces. Every year, large amounts of money are spent on replacing the worn out parts of these furnaces which are no longer usable because of corrosion. One of the key causes of corrosion in electrical arc furnaces is the thermal radiation from the arcs. If the arcs are not properly covere...
