Abstract:

This paper presents levels of harmonic voltage distortion with low-voltage customers during 2017 and 2018. Measurements were obtained over a period between one hour and one day per location. Results are presented for the harmonics in the phase-to-neutral voltage at 163 locations; the highest 10-minute values per location have been used for presenting the results. For harmonics in the neutral-to-ground voltage, 1-second values at 88 locations have been used. The harmonic levels showed to be well below the limits in EN 50160 and IEC 61000-2-2 for almost all locations and for all harmonics with exception of harmonics 9, 15 and 21. The dominating frequencies at most locations are harmonics 5 and 7.
