Static Synchronous Compensator, also known as SVG (Static Var Generator)
The dust filter can not be cleaned regularly, the dust and water will be inhaled into power modules, and then, the mud will be attached to power boards.
Cooling air will change direction after they come through basement louvre, then go up to enter the container through dust filter at the bottom of STATCOM. After heat exchange, hot air will be forced to go out from container back. The gravity of sands will sink after changing direction from basement louvre. This solution is very suitable for sands area.
