The GGJ Low-Voltage Intelligent Reactive Power Compensation Device effectively improves the power factor of electrical loads, reduces line losses, and enhances the actual load capacity of transformers, delivering significant energy-saving effects. By incorporating specific reactors in the system, it can also effectively prevent harmonic amplification and absorb most harmonic currents, ensuring that the total harmonic voltage distortion rate and the content limits of each harmonic current comply with national standards, thereby achieving harmonic mitigation. This product utilizes microcomputer control to intelligently track and compensate reactive power. With its rational structure and advanced technology, it is suitable for low-voltage power grids such as substations, production workshops in industrial and mining enterprises, and civil buildings. It is particularly suited for power transmission and distribution systems with frequently varying loads and unstable reactive power. It plays a notable role in improving the power factor, reducing reactive power losses, and enhancing power supply quality, making it a new generation of energy-saving product.
