Harmonics Filter's USAge had been widely recommended to overcome harmonics problem which occurred because of non-linear load presence in many industrial plants and manufacturing machines. On the previous research[1,2] it is obvious that both Active Filter and Hybrid Active Filter in Parallel Configuration made a satisfaction results for damping voltage and current harmonics. This paper descript in more depth on one of many types in harmonics filter named Hybrid Active Filter in Serie-Serie Configuration, thus it simulated to reduce harmonics that happened in a load such as vacuum casting induction furnace 9 kW, 13.8 kVA, 200V, 3 Ph, 50/60 Hz. The methods used still the same with the previous filter's simulated. This research (Hybrid Active Filter in Serie-Serie Configuration) produced on %ITHD for 11.86 % and %VTHD for 1.88%. In this case, both %ITHD and %VTHD are fulfilling IEEE 519.
