YDX-GS Dual-Circuit Anti-harmonic Intelligent Power Capacitor
YDX-GS
Integrated design, centralized reactive power compensation for power distribution system, local power factor correction for motor equipment, energy-saving system based on power factor correction.
The YDX series dual-circuit harmonic-resistant intelligent power capacitor is a new generation of reactive power compensation equipment designed for 0.4kV low-voltage power grids, offering high efficiency and energy savings, reducing line losses, improving power factor, and optimizing power quality. It consists of an intelligent measurement and control unit, a zero-crossing switching unit, a protection unit, a filter-tuned reactor, and low-voltage filter power capacitors. This new generation of low-voltage reactive power compensation equipment, which replaces the bulky and heavy structure of traditional reactive power compensation devices, offers improved compensation effectiveness, a smaller footprint, lower power consumption, a lower price, greater cost savings, greater flexibility, easier maintenance, a longer service life, and enhanced reliability. It is designed for use in environments with severe harmonics, operates reliably without resonance, and has no harmonic amplification effect, while also absorbing and eliminating harmonics to a certain extent. Models with a 7% series reactor are suitable for environments dominated by 5th harmonics (and above), while models with a 14% series reactor are suitable for environments dominated by 3rd harmonics (and above).
