Harmonic Correlations Matrices to Present Measurement Results from Single and Multiple Locations

• This paper presents results of harmonic voltage measurements at multiple locations in a low voltage network. Measurements were performed in different residential, industrial and commercial urban areas in the north of Sweden. This paper shows existing level of individual harmonics in these locations as a sample of an urban load and compares the harmonic variation between these points. The results showed during this period, characteristic harmonics are well below the standard limits. Correlation matrix is used for investigating possible correlation between individual harmonic orders in this urban area. It is observed that there is a significant correlation between 5th, 7th and 11th harmonic levels of low voltage customers connected to a common 10-kV network.
