Modern power analyzers cover the frequency range above the classical harmonics up to 2.5 kHz, while the measurement of supraharmonics is simplified with the universal broadband module PQE UBM from PQ ENGINEERING.
Measuring supraharmonics is important, but reducing them must be the goal!
More and more modern network analyzers are covering the frequency range above the "classic" harmonics up to 2.5 kHz for power quality measurements. Today, it's almost standard to measure and analyze voltage levels up to 9 kHz or even higher. In our daily network analyses, we see a rapid increase in interference levels at frequencies up to 20 kHz! Chargers in electric vehicles, converters with their clock frequencies, lighting systems, and many other consumers are generating interference at increasingly higher frequencies.
Measuring supraharmonics is an important measure, but only lowering the voltage levels eliminates the problem. Supraharmonics cause control system malfunctions, electronic component failures, noise, and much more.
This is where the universal broadband module PQE UBM from PQ ENGINEERING comes into play: https://lnkd.in/epwDEarF. The UBM filter module from the PQE hMF line filter kit reduces supraharmonics up to 20 kHz, dampens resonance points, and filters common-mode and differential-mode interference from the supply network. Its compact design and low losses facilitate retrofitting and integration into active filter cabinets.
