M.Ing. / \Vith electrical power networks expanding beyond their original design limits and the various non-linear loads on the network, power quality has become an important issue in electrical engineering. Some of the largest non-linear loads on the power network are arc furnaces used to melt various metal orrs and scrap metal. In this study the focus is on fliCker as a power quality issue and more specifically the measurement and analysis methods of flicker at arc furnace installations. By measuring flicker and 3 phase voltage and current waveforms the effect of changes in arc furnace system parameters on flicker is determined. Various analysis methods based on statistical theory are described in this study. The aim is to gain a better understanding of flicker and arc furnaces to contribute to the current flicker knowledge base.
