Static Var Generator
Our Static Var Generator is an electronic reactive power compensation system for both capacitive and inductive power.
It has the same operating principle as an active filter; the SVG injects a current in the opposite direction to counteract the installation's non-useful power (inductive and capacitive), thus ensuring that the target cosφ is achieved.
The SVG instantly compensates and adjusts according to demand in a matter of milliseconds. It also compensates for phase-to-phase in unbalanced systems. The SVG is the perfect device for installations where there are strict penalties for the consumption of reactive power.
Traditional capacitor-type PFC systems take 20ms-40s to respond to a change in load. Their delay, combined with the stepped response performance, means that they are perpetually over- or under-compensating.
Key benefits
Instant compensation
The system has a response time below 20 ms, offering highly efficient operation thanks to the development of IGBT technology.
Minimal maintenance
It has no electromechanical components, so no spare parts are required.
Stable network voltage
The output current is not affected by fluctuations in the network voltage.
No resonance
SVG technology generates no resonance with the installation's harmonics.
