POWER QUALITY - MORE THAN JUST THE COMPLIANCE OF EMC Directives

Presently electricity producers and suppliers are responsible for ensuring that the public supply conforms to the power quality standard EN 50160. However, it is in their own interest for electrical plant operators to minimize disruptions to the grid and so reduce production losses caused by system faults.

In addition to problems such as harmonics and voltage dips there is also the more important issue of saving energy to preserve our resources. REO follows a holistic approach, under the title of „Power Quality“, which considers the needs of both the nertwork and the consumers.

Thus, the core activity of REO AG is to find the very best solutions for maintaining the quality of our power supply.

Power Quality Solutions

Products such as Line filters and reactors, dv / dt filters and reactors, sinusoidal filters, regenerative filter and the harmonic filter REOWAVEPassive contribute not only to  prevent  disturbances, but  to save energy, too .

For example, by using a REOWAVE passive filter, up to 30 % energy savings can be achieved.

These are just some of the solutions that we offer in the field of power quality for you. In addition to power reactors, EMC and harmonic filters , we also offer customized solutions and services like EMC measurements - talk to us !

  • CNW 8981-50 Hz

    REOWAVEpassive - harmonic filter 50 Hz/400V (IP20)

    CNW 8981-50 Hz
    • Nominal Voltage: 400 V
    • Rated current: 6 - 1200 A
    • Frequency: 50 Hz

    Reduce Harmonics - save up to 30% energy costs.


    The REOWAVE®passive filters harmonics caused by  the B6 circuit (thyristor, diode bridge, etc.) and motor drives. The supply network is relieved by compensating the harmonics reactive power. This enables cost savings in material selection and energy consumption. Starting currents and current peaks are greatly attenuated.


    This increases the service life and reliability of electrical systems. Due to the compact and ready-build  an easy installation is possible.


    The REOWAVE®passive helps to comply with international power quality standards IEEE 519 or EN 61000-3.

    • Inductance per strand: 0,05 - 25 mH

    Sinusoidal output current - save costs and trouble-free operation.


    For particularly long cable lengths of > 100m between inverter and motor the shielded cable for EMI suppression used can cause a capacitive coupling. A conventional motor choke can not provide sufficient damping in such cases.


    The sinusoidal filter is a low pass from inductance and capacitance and has a very low resonance frequency. So it is able to generate a largely sinusoidal current. The operation and the loss balance of the asynchronous motor behave like the normal mains operation. The typical motor noise with converter do not occur and a shielded cable to the motor can be dispensed. Losses and heating are greatly minimized and the leakage current will be reduced. Longer motor cable lengths are possible. The motor insulation is protected, thus increasing the service life.


    The sinusoidal filter also attenuates the conducted interference in lower frequency range very good. The losses and the typical noise in the motor plate can be reduced.
