Harmonic mitigation solutions

  • While variable speed drives help optimize production, save energy and extend equipment lifetime, they also introduce harmonic currents to the on-board grid. Many applications in the industry require a low level of harmonic distortion. Regulations have been imposed by marine certification bodies which state that harmonics must be kept to 5% or 8% of the total harmonic voltage distortion (THDv) on the main bus bar.

    Danfoss Drives’ wide range of mitigation solutions which can help restore weak networks, increase network capacity, meet compact retrofit demands or secure sensitive environments includes:

    • VLT® Advanced Active Filter AAF 006
    • VLT® Advanced Harmonic Filter AHF 005/AHF 010
