Intelligent Integrated Power Capacitors
YD-868
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 YD-868 intelligent integrated power capacitor is a new generation of reactive power compensation equipment with a high breaking capacity, offering high efficiency and energy savings for 0.4kV low-voltage power grids, reducing line losses, improving power factor, and enhancing power quality. It consists of an intelligent measurement and control unit, a zero-crossing switching unit, a protection unit, and two (△-type) or two (Y-type) low-voltage power capacitors. This eliminates the bulky and cumbersome structure of traditional reactive power compensation devices. This new generation of low-voltage reactive power compensation equipment 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 increased reliability, meeting the stringent reactive power compensation requirements of modern smart grids.
