Electronic compensation
With electronic compensation it is possible to compensate inductive, capacitive and harmonic reactive power. In addition, it is possible to eliminate imbalances in the flows phase. This creates extra power space, limits energy losses and prevents fines and claims.
In addition, the reduction of harmonic currents significantly improves the voltage quality, so that the connected equipment functions longer, more efficiently and more effectively.
The static VAR Generator (SVG) and Active Harmonic Filter (AHF) from Sinexcel are based on 3-level IGBT technology. This has resulted in compact units with a low weight suitable for wall and rack mounting. With the user-friendly color screen, the models are easy to operate.
Static VAR Generator (SVG)
The successor to the cos-phi bank
Capacitor banks are used in many installations to reduce reactive current. In modern installations, these capacitor banks often cause problems and active harmonic filters are too expensive.
That is why an electronic variant of the capacitor bank - based on 3-level IBGT technology - has now been developed: the Static VAR Generator.
Working principle of an SVG
A Static VAR generator (SVG) is a fast electronic and stepless reactive current compensation without capacitors. The SVG measures the inductive current [1] and injects a current which is phase-shifted with the voltage [2] such that the current for the filter [3] flows neatly with the voltage.
Properties of a Static Var Generator
- Compensate for both inductive and capacitive reactive power
- Eliminate imbalance in phase currents and create power space.
- Resistant to harmonic currents.
Typical application areas of a Static VAR Generator
- In capacitive networks where the emergency power generator does not come up properly
- To compensate for rapidly changing electronic loads
- In installations with unevenly loaded phases where more power space is required
- Eliminate imbalance in feed-in at solar parks
Advantages SVG over a capacitor bank
- Compensate for both inductive and capacitive reactive power
- Super fast response time (<20ms)
- Fast and stepless, so that over- or undercompensation is not possible
- More compact and lighter weight
- Less energy loss
- Not overloadable and insensitive to resonance and interharmonics
- Maintenance free

Active harmonic filter (AHF) - Sinexcel
Compensating for harmonic currents
With an active harmonic filter, harmonic currents can be compensated, creating additional power space and preventing machine and equipment failure.
The active filter is based on 3-level IGBT technology, making the filter compact and minimizing losses.
Working principle of an active harmonic filter (AHF)
An active harmonic filter filters harmonic currents with an operating principle based on the principle of “noise canceling”. The filter measures the current pollution [1] and injects a counter current [2] which is shaped in such a way that the current for the filter [3] becomes sinusoidal again. This compensates for all harmonic reactive power.
Inductive, capacitive and harmonic compensation
The harmonic filter is also able to compensate both inductive and capacitive reactive power, making such a filter universally applicable and not overloadable.
Properties of an active harmonic filter
- Elimination of harmonic currents
- Compensate for both inductive and capacitive reactive power
- Eliminate imbalance in phase currents and create power space
- Improve voltage quality
Typical applications of an active harmonic filter (AHF)
- Reduction of inductive, capacitive and harmonic reactive power
- Reduce problems with LED lighting, charging points and frequency-controlled motors
- Filter out harmonic currents and thereby improve voltage quality
Advantages of an active harmonic filter
- All power quality problems can be solved
- Compensate for inductive, capacitive and harmonic reactive power
- Equalize unevenly charged phases, creating additional power space
- Improve voltage quality
- Even more power space by limiting derating power transformer
- Super fast response time (<5ms) and continuous adaptation to the load
- Less losses, lower footprint
- Not overloadable and insensitive to resonance and interharmonics

Advanced Static VAR Generator
The best solution for reducing reactive power and filtering out the most common harmonic
In most installations the reactive power consists of so-called inductive reactive power (poor cos-phi) and harmonic reactive power caused by current harmonics up to the 9th order. The ASVG was developed precisely for this application.
As with the SVG, the ASVG can be used to reduce inductive or capacitive reactive power. In addition, 50% of available compensation capacity can be used to reduce harmonic through 11th order. This means that for most installations, the ASVG is the most effective solution for reducing reactive power.
As with the AHF and the SVG, the ASVG is based on IBGT technology - developed. That means small dimensions, light in weight and low losses.
