How Not To – Out-dated Measurement Approach
Analysing the effects of Supraharmonics asks for Power Quality Analyzer that cover a frequency range up to 500 kHz. Classical PQ Analyzers present problems because of their limited bandwidth. Typically they can measure up to the 50th Harmonics (2.5kHz), but cannot detect higher emissions of voltage and currents. By design, they are not able to be used in the troubleshooting process at all.
