- Commodity name: GGJ Low-Voltage Reactive Power Intelligent Compensation Device
Because this device can effectively improve the power factor of the electrical load, reduce line losses, and enhance the actual loading capacity of transformers, it delivers significant energy-saving benefits. Moreover, by incorporating specific reactors into the system, it can effectively suppress harmonic amplification and absorb most harmonic currents, ensuring that the total harmonic distortion of voltage and the limits on the harmonic current content at each order comply with national standards, thereby achieving the objective of harmonic mitigation.
Overview
Because this device can effectively improve the power factor of the electrical load, reduce line losses, and enhance the actual loading capacity of transformers, it delivers significant energy-saving benefits. Moreover, by incorporating specific reactors into the system, it can effectively suppress harmonic amplification and absorb most harmonic currents, ensuring that the total harmonic distortion of voltage and the limits on the magnitude of each harmonic current comply with national standards, thereby achieving the objective of harmonic mitigation. In contrast, using conventional contactors to switch capacitor banks results in large inrush currents, slow compensation response times, high maintenance costs, and a short service life. Therefore, we recommend that users give priority to dynamic reactive power compensation devices in the following applications: low-voltage distribution networks in substations, production workshops, and civil buildings of industrial and mining enterprises—particularly in transmission and distribution systems where loads frequently fluctuate and reactive power is inherently unstable.
This product complies with standards including GB/T 15576-2008 “Low-Voltage Complete Reactive Power Compensation Equipment” and IEC 60439 “Low-Voltage Switchgear and Controlgear Assemblies.”Model and Meaning
