Harmonic Filter

Power quality is a major concern for manufacturers and power plants. Power quality issues arise due to harmonic disturbances and reactive power generated by unbalanced loads, variable frequency drives and motors. These issues have serious consequences of which include: prematurely aged equipment, energy loss, poor functioning controls and circuits and increased energy, component and transformer costs.

With more than 20 years radio frequency interference experience, Finmotor developed the harmonic filter series to solve harmonic disturbance and power quality issues by compensating current harmonic and power factor correction.
