ENGINEERED SOLUTION
Steel & Metallurgy
Power factor correction, harmonic mitigation and voltage support for electric arc furnaces, rolling mills, cranes and high-load metallurgical production lines.
Filter Reactors
LKSG series filter reactors are connected in series with power capacitors to form LC resonant branches in harmonic filtering cabinets. By providing inductive impedance at designated harmonic frequencies, the filter branches absorb local harmonic currents and prevent them from propagating through the grid.
LKSG Series Filter Reactors (Tuned Filter Reactors)
Product Introduction
LKSG series filter reactors are connected in series with power capacitors to form LC resonant branches in harmonic filtering cabinets. By providing inductive impedance at designated harmonic frequencies, the filter branches absorb local harmonic currents and prevent them from propagating through the grid.
These reactors improve system power factor, reduce voltage waveform distortion, mitigate network pollution, and enhance overall power quality in harmonic-rich industrial and commercial power systems.
