Supraharmonics in European and North American Low-Voltage Networks

This paper presents the measurement and characterization of voltage supraharmonic emission (in the frequency range 2–150 kHz) at different European and North American low-voltage networks. This knowledge is needed to be able to better predict the impact of new equipment on the voltage and current distortion in the low-voltage network. This work presents a discussion serving as a guide for future standardization of voltage supraharmonic levels, as it presents an overview of real values measured in the power grid in different countries.
