Product profile

The CY-LRSGD filter reactor applies to VAR compensation and harmonic suppression systems. When connected with the capacitor, the filter reactor can generate the min. or max. impedance using its physical property - LC resonance to absorb or block the harmonic voltage and current of corresponding frequency in the grid, thus eliminating the harmonics and maintaining the power factor of the system at the optimum value to significantly improve the power quality of the grid.
