- Commodity name: GGJ Low Voltage Reactive Power Intelligent Compensation Device
This device can effectively improve the power factor of electrical loads, reduce line losses, and enhance the actual load capacity of transformers, resulting in significant energy-saving effects. Additionally, by using specific reactors in the system, it can effectively prevent harmonic amplification and absorb most of the harmonic currents, ensuring that the total harmonic distortion voltage limits and the content limits of each harmonic current comply with national standards, thus achieving the goal of harmonic management.
This device can effectively improve the power factor of electrical loads, reduce line losses, and enhance the actual load capacity of transformers, resulting in significant energy-saving effects. Additionally, by using specific reactors in the system, it can effectively prevent harmonic amplification and absorb most harmonic currents, ensuring that the total harmonic distortion limits and the content limits of each harmonic current comply with national standards, achieving the goal of harmonic treatment. If ordinary contactors are used to switch capacitor groups, it will lead to large inrush currents, slow compensation times, high maintenance costs, and short service life. Therefore, we recommend that users consider using dynamic reactive power compensation devices in the following situations: in substations of industrial and mining enterprises, production workshops, and low-voltage power grids of civil buildings, especially suitable for power distribution systems where loads frequently change and reactive power is unstable. This product complies with: G8/T15576-2008 "Low Voltage Complete Reactive Power Compensation Equipment", IEC60439 "Low Voltage Complete Switchgear and Control Equipment", and other standards.
