I. Overview:

The GGJ low-voltage reactive power intelligent compensation device adopts computer-aided design (CAD), introduces microcomputer control, and implements intelligent tracking compensation for reactive power. Its structure is reasonable, technology is advanced, and it is widely used in low-voltage power grids to improve power factor, reduce reactive power loss, and improve power supply quality. It is a new generation of energy-saving products. Dedicated to reactive power compensation for three-phase transformers with a capacity of 130-600KVA.

II. Product Features

1. It is controlled by an intelligent controller and has complete functions. Reliable performance, automatic compensation method; Can increase the power factor to 0.9 or above;

2. Real time display of power factor of the power grid, display range: lag (0.00-0.99), lead (0.00-0.99);

3. It has various comprehensive protection functions such as overvoltage, subharmonics, overcompensation, system faults, phase loss, overload, etc;

4. Memorize the set parameters, and the system will not lose the parameters after a power outage. After the power grid returns to normal, it will automatically enter the operating state without the need for personnel to be on duty;

5. According to the load balance of the power grid, phase separation compensation or mixed compensation can be adopted;

6. Strong anti-interference ability, able to withstand 2000V interference pulses directly input from the power grid, higher than national professional standards.

III. Distribution network monitoring function
