With the development of reactive power compensation technology, for three-phase unbalanced loads, the method of separately switching capacitors for each phase can be employed to compensate for the reactive power of each phase.

This approach enhances compensation accuracy and improves energy-saving effects. To achieve this, our company has developed a parallel capacitor configuration that enables both phase-by-phase and inter-phase compensation, facilitating the selective switching of capacitors for different phases.

These capacitors possess a higher ability to withstand currents and are connected in series with reactors to suppress harmonic current amplification and prevent resonance. Additionally, this product functions as a reactive power compensator.
