FGI 6kV~6.6kV Indoor Type Static Var Generator – Advanced Power Quality & Grid Stability

 

 

Features & Functions

 

• Extreme Ride-Through:

Our SVG quickly restores normal operation after grid voltage dips or surges, adapting to various grid conditions without manual intervention.

• Voltage Fluctuation Suppression:

For fluctuating loads like arc furnaces, our SVG dynamically provides reactive current to quickly stabilize voltage and suppress flicker.

• Reliable Dual Power:

The control system features a dual power supply (380VAC/220VAC or 220VDC) with seamless online backup switching, ensuring continuous operation even if one source fails.

• EMC Compliant Enclosure:

Our cabinet boasts an anti-interference design, passing rigorous EMC tests for robust performance in challenging electromagnetic environments.

• Redundant & Stable System:

Options for a dual-master control system and automatic bypass for power units ensure high availability and stable operation, even with component faults.
