GGJ Reactive Power Compensation Low Voltage Cabinet
Since the low voltage cabinet can effectively improve the power factor of the power load, reduce the line loss, improve the actual load capacity of the transformer, and has significant energy saving effect, and adopting a specific reactor in the system, the harmonic amplification and effective absorption can be effectively prevented.
Since the low voltage cabinet can effectively improve the power factor of the power load, reduce the line loss, improve the actual load capacity of the transformer, and has significant energy saving effect, and adopting a specific reactor in the system, the harmonic amplification and effective absorption can be effectively prevented. Most of the harmonic currents make the harmonic voltage total distortion rate limit and the harmonic current content limit meet the national standards and achieve the purpose of harmonic control.
Low voltage cabinet such as substations, production workshops and civil buildings of industrial and mining enterprises, it is especially suitable for transmission and distribution systems with frequent load changes and unstable reactive power.
