A REVOLUTIONARY NEW POWER FACTOR SYSTEM – STATIC VAR GENERATOR (SVG)

​

Automatic power factor correction equipment is broadly applied in NZ industry to ensure the electrical network is utilised to its best capacity. The usual form of such power factor correction is an automatic controller that monitors one incoming phase to a plant and switches banks of capacitors to try and maintain a target power factor.

​

Problems to be Solved:

Slow reacting capacitor

Capacitor Overload

Short Life of Equipment and System

Contactor Failures and overloaded capacitor leaks

Fire Risk for Contactor Failures.

Sinexcel’s SVG is an entirely new approach to power factor correction. The SVG utilises a high speed three level inverter that reacts to changes in reactive power, exchanging corrective reactive power into the system. Full correction is made in 3/4 of a cycle. This rapid response provides stable accurate real-time power factor correction without the drawbacks of traditional capacitor based systems. The SVG can continuously adjust reactive power dynamically and bi-directionally (leading or lagging). There is no chance of system resonance and even under low voltage conditions SVG will provide full reactive power compensation. The Sinexcel SVG is 100% inverter based so there are no AC capacitors to fail.
