GGJ-Type Low-Voltage Reactive Power Compensation Device
It is mainly composed of stainless steel box, integrated power distribution measurement and control instrument, composite switch, capacitor, communication terminal, single-bank capacitor protector, lightning arrester, main power switch, sampling and measurement transformer, and capacitor bank operation status indicator.
The reactive power compensation features fast response, and the automatic switching of capacitor bank. The response time of each capacitor bank switching is 20-55s. The new reactive power control algorithm can be used to perform phase compensation under unbalanced conditions to set the power factors of each phase within the designed range. It is also characterized by modular design, simple installation, convenient maintenance, a long service life, and a high reliability to achieve impact-free and low-inrush current switching. The device has proven self-diagnosis and multiple protection functions.
