Supraharmonics are emissions in the range of 2 kHz – 150 kHz cause a multitude of problems for grid operators and customers alike, but are only just being discovered and measured.
International researchers used PQube 3 to gather measurements from locations worldwide to quantify the impact of high frequency emissions in distribution grids. Their recent paper, “Supraharmonics in European and North American Low-Voltage Networks” presented at the IEEE EEEEIC 2018 International Conference on Environment and Electrical Engineering in Palermo Italy, discusses how new and existing distribution grid technologies (PLC, DERs, power electronics, etc.) are contributing to this new type of pollution.
Do you experience unexplained equipment failure while your power quality analyzer doesn’t report any issues? Open up the scope to 360 degree, including supraharmonics detection.
One instrument that is enabling ultra-precise measurement is our own PQube 3, which is certified for Class A power quality according to IEC 61000-4-30 Ed3, and holds years of data and thousands of events via 32 GB of internal flash memory. It’s ideal for troubleshooting sensitive or critical mission equipment in factories, labs, data centers, and many other applications.
