To provide the best power quality solutions, the most crucial aspect is measurement and analysis to identify power quality issues. Our company performs power quality measurements using devices compliant with standards such as EN50160, IEC61000-2-2 / IEC61000-2-12, and IEC61000-2-4, capable of transient analysis up to 5kV, sinusoidal resolution up to 4MHz, and resonance analysis up to 170kHz. We assess power quality according to the IEC61000-4-30 Ed. 3 standard, Class A, which recently categorizes various power quality problems under the “harmonic” classification. Contrary to common perception, issues like resonance, voltage events, transients, common mode currents/voltages, and EMC are distinct problems requiring individual examination and tailored solutions. Our company conducts comprehensive power quality measurements, including harmonic analysis up to the 50th harmonic, harmonic analysis between 2-9kHz, and supraharmonics analysis up to 170kHz, enabling rapid identification of these issues at their source. These measurement results are analyzed by our experienced technical team, allowing us to provide our customers with the most accurate and appropriate solutions. These solutions encompass filters and reactors from our own production, as well as filters imported from our quality-leading solution partners worldwide.

Power Quality
What is Power Quality?
Power quality is a standard that must be ensured in electrical systems. It refers to the transmission of electrical energy at desired performance levels, and within the parameters and limits set by national and international standards. Power quality plays a critical role in identifying and resolving any problems in electrical systems. The growing demand and rapid technological advancements in electrical systems have led to an increase in power quality concerns. Consequently, measuring power quality holds substantial significance in enhancing the reliability and performance of electrical systems.
How is Power Quality Measurement Performed?
Power quality is determined through measurements that assess diverse electrical characteristics in electrical systems to ensure their compliance. These measurements are typically conducted by electrical engineers, who analyze data obtained from the systems. Through this analysis, potential problems in the system are identified, and recommendations for solutions are provided. Power quality measurement helps enhance the reliability and performance of electrical systems by addressing following parameters.
- Harmonic
- Flicker
- Variation in voltage levels
- Imbalance in current and voltage phases
- K factor consideration
- Fluctuations in frequency
- Potential difference between neutral and earth
- Transient
Power quality problems can arise in a wide range of areas, from the user’s installation to the power distribution system. By analyzing the measurement data, the source of the problem is identified, enabling the development of tailored solutions to address it.

Harmonix – Serial Passive Harmonic Filter
Serial Passive Harmonic Filters are a series of passive harmonic filter solutions designed to mitigate harmonic distortions in electrical systems. Utilized in systems with high harmonic content, they serve to decrease harmonic currents, enhance power quality, and minimize the risk of device damage.

Sine Wave (Sinusoidal) Filter
Sine Wave filters, are devices that filter harmonic components in electrical systems, transforming them into pure sinusoidal waveforms. This functionality helps protect sensitive electrical equipment and reduces harmonic distortions within the system.

Line Reactors
Line reactors mounted at the input of variable frequency drive, serve to diminish the harmonics generated by the device into the grid, while also safeguarding the device against voltage spikes originating from the grid.

Load Reactors
Load reactors are devices that shield motors from over-voltage and over-currents. They ensure the reliability of motors and assist in preventing faults that could arise from overloads.

Smoothing Reactors
Smoothing reactors are devices utilized to regulate fluctuations in electrical systems. They are employed to rectify fluctuating DC voltage on the DC bus.

SOFIA – Voltage Controlled Harmonic Filter – Condensator Dominit
SOFIA – Voltage Controlled Harmonic Filter, produced by Condensator Dominit in Germany, mitigates voltage harmonic distortion levels below industry standards. This is achieved by filtering the harmonic currents that arise from variable frequency drives and other harmonic-generating loads within facilities.

RESI – Resonance – Condensator Dominit
Resi, produced by Condensator Dominit in Germany, functions as a resonance filter and mitigates resonance issues in electrical systems. By addressing imbalances in the system, it improves overall system performance and prolongs the operational lifetime of equipment.

Active Harmonic Filter
Active Harmonic Filter, developed and produced by Comsys in Sweden, is a device that efficiently mitigates harmonic current distortions in electrical systems. By delivering feedback to the system, it counterbalances harmonic currents and improves the system’s power quality.

P200 – Resonance Filter – Comsys
P200, a device designed and produced by the Swedish company Comsys, functions as a resonance filter that addresses resonance issues in electrical systems. This system demonstrates exceptional capabilities in mitigating power quality problems, including resonances and supraharmonics
