supraharmonics

Noun

supraharmonics pl (plural only)

1. (plural, plural-only) Distortions to the current and voltage flow in power distribution lines that occur in the range of 2kHz-150kHz
   • The two main sources of supraharmonics that have been identified are power-electronic converters with active or passive switching (non-intentional emission) and transmitters of power-line communication (intentional emission).2016, Sarah Rönnberg, Math Bollen, “Power quality issues in the electric power system of the future”, in The Electricity Journal, volume 29, number 10, page 57
   • The term "supraharmonics" was first introduced in 2013 during the summit entitled "IEEE Power & Energy Society" to indicate any kind of voltage and current waveform distortion within the range of frequencies from 2 to 150 kHz.2023 Jan, Michalec, Łukasz, Kostyła, Paweł, Leonowicz, Zbigniew, “Supraharmonic Pollution Emitted by Nonlinear Loads in Power Networks—Ongoing Worldwide Research and Upcoming Challenges.”, in...
