Product Introduction
Product Overview
The GGJ Low-Voltage Reactive Power Intelligent Compensation Device can effectively improve the power factor of electrical loads, reduce line losses, and enhance the actual load-carrying capacity of transformers, delivering significant energy-saving effects. Meanwhile, by adopting specific reactors in the system, it can also effectively prevent harmonic amplification and absorb most harmonic currents, ensuring that the total harmonic voltage distortion limit and the harmonic current content limit of each order comply with national standards, thus achieving the goal of harmonic mitigation.

This device incorporates a microcomputer control system to implement intelligent tracking and compensation of reactive power. It features a reasonable structure and advanced technology, making it suitable for low-voltage power grids such as substations, production workshops of industrial and mining enterprises, and civil buildings. It is particularly well-suited for power transmission and distribution systems where loads change frequently and reactive power is unstable.
It plays a significant role in improving the power factor, reducing reactive power losses, and enhancing power supply quality, and is therefore a new generation of energy-saving products.
