Electric Arc Furnaces (EAF) are huge energy consumer. However due a limited power calculation the maximum electrical efficiency is not obtained. Most of the applications in market report the usage of inaccurate power quantities in EAF power control system. Because the extreme distortion conditions of power phenomena produced by the nonlinearity of the load in the EAF, the implementation of Current’s Physical Components (CPC) power theory has the potential of describing more appropriate than traditional power theories the physical load conditions and the electric power phenomenon during the Heat Process. Each one of the current components proposed by CPC offer useful information of the load condition, and give indicators which can be useful as stability indicators of the process for a better identification of the EAF stage.

Piece łukowe rzadko osiągają maksymalną skuteczność. Zastosowanie metody Current Physical Component pozwala bardziej dokładnie analizować warunki obciążenia podczas wyładowania i tym samym osiągać mniejsze zniekształcenia i lepszą skuteczność.
