Power Quality Components

The CKSC high-voltage iron-core series reactor is connected in series with capacitor banks to limit switching inrush current and control harmonic amplification in medium- and high-voltage compensation systems. Dry-type and oil-immersed configurations are selected according to system voltage, capacitor capacity, reactance ratio and installation conditions for substations and industrial distribution networks.

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.

Filter/compensation modules are integrated functional units designed for reactive power compensation and harmonic mitigation in low-voltage power distribution networks. Each module combines key components such as capacitors, detuned reactors, contactors, fuses, busbars, and terminals into a compact and standardized structure.

The HYRPC-130E series is an intelligent reactive power compensation and voltage quality control device, designed for 1 to 3 capacitor banks in low-voltage distribution systems such as single-transformer substations and single-source feeders.

With the increasing number of harmonic-generating loads in modern industrial and commercial power systems, harmonic distortion has become a significant threat to grid stability and equipment performance. Harmonic resonance and voltage waveform distortion may lead to overheating, malfunction, or even severe failure of electrical equipment.

This all-in-one structure replaces multiple traditional components such as reactive power controller, fuses/MCBs, thyristor switches/contactors, thermal relays, indicator lamps, and stand-alone power capacitors.
