GRIDVAR Static Var Generator

Stepless reactive power compensation. Rated in kvar — sizing follows a reactive power calculation. Three technology tiers on one hardware platform.

GRIDVAR · SVG family

Stepless Reactive Power Compensation

Its primary function is reactive power compensation. It is rated in kvar — sizing follows a reactive power calculation. Harmonic suppression comes from residual capacity. The three tiers share one body platform; what differs is performance and budget.
