    Análise da influência da configuração do alimentador nas impedâncias de fase das linhas elétricas de distribuição
    (2012) García, Felipe Hernández; Oliveira, Mario Orlando; Ferraz, Renato Gonçalves; Bretas, Arturo Suman
    This paper present a numerical study of the feeder configuration influence on the phase impedance matrix components of the distribution line. As variables for analysis were used the phase and neutral conductor spacing on the structure of the distribution power system. Furthermore, different conductor were used in analyse to checking the conductor type influence. The results obtained showed that different phase-neutral conductors’ combinations can lead to similar phase impedance in the electric line. On other hand, it was found that the mutual impedances of the electric line change significantly with the displacement of the phase conductors and the neutral conductor displacement alters the impedance phase value. The results of this study were verified using the routine "Cable Constant" of the simulator ATP (Alternative Transient Program).
