product description
GGJ low-voltage reactive power intelligent compensation device can effectively improve the power factor of electrical loads, reduce line losses, and increase the actual load capacity of transformers. It has significant energy-saving effects. At the same time, the use of specific reactors in the system can also effectively prevent harmonics. Amplify and effectively absorb most of the harmonic currents, so that the total harmonic voltage distortion rate limit and each harmonic current content limit comply with national standards, achieving the purpose of harmonic control. It introduces microcomputer control to implement intelligent tracking and compensation of reactive power. It has a reasonable structure and advanced technology. It is suitable for low-voltage power grids such as substations of industrial and mining enterprises, production workshops and civil buildings. It is especially suitable for frequent changes in load and reactive power. Transmission and distribution system with unstable power. It has a significant effect on improving power factor, reducing reactive power loss and improving power supply quality. It is a new generation of energy-saving product.
Model and its meaning
main feature
1. It is controlled by an intelligent controller and has complete functions. Reliable performance, automatic compensation mode; can increase the power factor to above 0.9;
2. Real-time display of grid power factor, display range: lag (0.00-0.99), lead (0.00-0.99);
3. With over-voltage and over-harmonics , over-compensation, system failure, phase loss, overload and other comprehensive protection functions:
