Frequently Asked Questions (FAQ)

What are the capacity ratings and voltage levels of the SVG modules?

The SVG modules support capacity ratings of 50kvar and 100kvar, and operate across a wide voltage level range from 400V up to 35kV.

How fast is the response time of the SVG compared to conventional technology?

The SVG features an extremely rapid response time of ≤1ms, offering a significant advantage over the slow response speeds typical of conventional technologies.

Can the SVG compensate for both capacitive and inductive reactive power?

Yes. Unlike conventional systems that cannot compensate for capacitive reactive power, the SVG provides both capacitive and inductive compensation with stepless and accurate control.

Does the SVG support parallel module operation for expansion?

Yes, the SVG features a modular design for easy capacity expansion. It supports unlimited parallel operation, with a maximum of 6 modules manageable under a single SAM controller.

How does the SVG handle harmonics and resonance issues?

The SVG suppresses harmonic resonance and offers optional active filtering settings, providing a maximum of 10% filtering capability up to the 13th order.

What physical and operational advantages does the SVG offer over older technologies?

The SVG is highly compact, requiring less physical installation space. Operationally, it produces no surge current during startup and features free load unbalance compensation.
