Measurements of Harmonic Voltages at Multiple Locations in LV and MV Networks

• This paper presents harmonic voltage measurements for a part of a distribution network including low-voltage (400 V) and medium-voltage (10 kV). Measurements were performed during 2017 and 2018 in the north of Sweden. This paper shows correlations between different harmonic orders in low voltage and the correlation between low and medium-voltage harmonics. This information can be used for harmonic propagation studies in distribution networks. The results showed significant correlation between the 5 th and 7 th harmonics for low-voltage side and very high correlation between 5 th harmonic order in low-voltage and medium-voltage. It is also observed that 5 th harmonic has almost the same values for all transformers connected to the same 40 kV network.
