Abstract :
This work presents results of the current harmonics analysis in a three-phase network with nonlinear single-phase loads. In this analysis, typical single-phase nonlinear loads such as computers. monitors and printers, were considered. Simulation results are accompanied with field measurements. A mutual influence of single-phase loads connected in different phases,of the network is studied. Factors having an effect on harmonic content of a neutral conductor current, are investigated in the present work. The causes for the excessive neutral conductor current are explored and the dominant role of the triple harmonics is highlighted.
