Filtro de armónicos

SUPRESIÓN DE CORRIENTES ARMÓNICAS
Y CUMPLIMIENTO DE NORMAS CEM

Los filtros de armónicos REO se utilizan para reducir la distorsión total de armónicos
(THD por sus siglas en inglés). Las corrientes armónicas se suprimen con tal intensidad que se alcanza una THD inferior al 5%. Además, gracias a un filtro de armónicos (p. ej. REOWAVEpassive) la potencia reactiva se reduce y se ahorra hasta un 30% de energía.

¿Por qué es conveniente montar un filtro de armónicos de forma adicional?

- Reducción del valor THDI por debajo del 5%

- Aumento de la estabilidad de la red

- Cumplimiento de las normas IEEE 519, EN 61000-3-12, EN 61000-3-2 , EN 61000-3-4

  • CNW 897

    Three-phase harmonic filter (400 V/50 HZ)

    CNW 897
    • Tensión nominal: 400 V
    • Corriente nominal: 25 - 600 A
    • Inductance of the choke: 0,2 - 2,9 mH

    The filter is designed for the reduction of the THD (Total Har-monic Distortion) when used with B12 rectifiers. The harmonic currents are extremely suppressed so that the THD is reduced to lower than 5 % (for example in UPS-systems)


    Typical values of Total Harmonic Distortion with B12 rectifiers and use of transformers are between 12 and 13%. This complies with the EN 61000-3-4 and EN 61000-3-12 standards.


    If more severe conditions for the mains are defined, in addition to the transformer it is necessary to use REO-Harmonic-Filter type CNW 897. These filters are available in two different versions:



    • THD < 5%

    • THD < 10 %


    The IP00 version is especially suitable for panel mounting and can be mounted to save space here. The CNW 897 helps to comply with international power quality standards IEEE 519 or EN 61000-3 .

  • CNW 8981 - 60 Hz

    REOWAVEpassive - harmonic filter 60 Hz/480 V (IP20)

    CNW 8981 - 60 Hz
    • Tensión nominal: 480 V
    • Corriente nominal: 9 - 1200 A
    • Frecuencia: 60 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.
