Soothing Equipment of harmonics and compensating reactive power have been widely discussed and applied successfully in recent years in the most varied industrial and commercial installations, encouraged by eliminating the fine for low power factor and by problems arising out of the significant increase in nonlinear loads connected to these electrical systems. Currently, various types of equipment that do the dual function of reducing harmonic content and power factor correction are applied using simulation techniques and well-known studies (through programmes computational load flow and flow harmonics) to ensure the most appropriate field response. In this sense, the proposed work is to show a technical-economical comparison between the equipment most frequently used as a solution of power factor and problems with harmonics, being them: Bank capacitors, passive harmonic filter detuned, passive harmonic filter tuned active harmonic filter, and harmonic hybrid filter. Evaluates the performance of each of these equipment mentioned above, where the following technical aspects will be assessed: voltage, current effective, total harmonic distortion of voltage (DTT), total harmonic distortion of current (DTI), active power, reactive, apparent, harmonic distortion and power factor. Simulations with the application of all types of equipment cited, power factor correction and filtering of harmonics, provide results with their respective implementation costs. Finally, the results obtained will be presented by monitoring in the field of the main electrical magnitudes in analysis, the solution adopted in the light of better cost x benefit and the performance of equipment installed for the desired by the company consumer goals.
