Harmonisk forvrængning

  • Hvordan opstår harmonisk forvrængning?

     

    Harmonisk netforvrængning opstår blandt andet på grund af industriens øgede brug af frekvensomformere, UPS anlæg og belysningsanlæg, samt andre elektriske komponenter som har en switchmode strømforsyning.
    Harmoniske strømme, eller ikke-sinus formede strømme, kan resultere i en forvrængning af forsyningsspændings-kurven til at være ikke-sinusformet. Harmonisk netforvrængning har flere negative konsekvenser.
    Blandt andet kan det forårsage:

    • Reduceret driftssikkerhed 
    • Forringet forsyningskvalitet 
    • Øgede driftsomkostninger 
    • Større slid og kortere levetid på systemkomponenter

     

  • Harmonisk simulering

    Med en simulering af harmoniske forstyrrelser inden du går i gang med at installere, kan du minimere uforudsete udgifter til indkøb af udstyr til reduktion af harmonisk netforvrængning.

    Du får en detaljeret rapport, der viser harmonisk forvrængning i de enkelte dele af installationen.

    Udfyld formularen og send den udfyldte formular via mail til vlt.dk@danfoss.dk.

     

  • Harmonisk måling

    Vil du vide om din installation overholder gældende standarder, kan vi hjælpe med en on-site harmonisk måling med Fluke 435 effektkvalitets- og energianalysator.

    Målingerne resulterer i en rapport, der dokumenterer om installationen overholder gældende harmoniske niveauer i IEC 61000-2-2 eller anden relevant standard.
