The practice of operating multiple single-tuned filters in AC electrical arc furnace power supply systems has shown, that frequent energizing unloaded furnace transformer can cause damage of the filters. To examination of supply and filter system configuration impact on switching transient and dynamic overvoltages and overcurrents, an example of 50 MVA arc furnace unit was chosen. The transient analysis has been carried out by simulating within Matlab/Simulink Software. Using ANSI/IEEE Standards paper focuses on the selections of ratings for capacitors and air-core reactors used in multiple single-tuned harmonic filters configurations. Comparison of filter reactor and capacitor bank design based on steady state operation and transformer energizing was shown.
