The practice of operating AC electrical arc fumace power supply systems has shown that energizing unloaded fumace transformer can cause long lasting transients in filter circuits of static VAR compensators used in the supply systems. Examination of the supply system configuration impact on switching transient behaviour has been carried out by example of a 50 MVA arc fumace unit. The transient analysis has been carried out through simulating by Matlab/Simulink software.
