THE INFLUENCE OF THE DEFORMANT AND NON SIMETRIC PROCEDURE ON THE NULL CONDUCTOR IN THE LOW VOLTAGE INSTALLATIONS

摘要

The paper presents general aspectsregarding the nature of loads that are generated andcirculate in low voltage networks, the influence on thenull conductor and the calculation of the actual valueof the current on the null. The paper considers themeasured values of null current in networks withdeforming and unbalanced loads related totransformer stations. The calculation of power andenergy losses in symmetrical and non-symmetricalbalanced three-phase networks allows thedetermination of the CPT growth rate (owntechnological consumption) and its comparison withthat determined from the graphs given by thestandards. Balancing measures of phase loading andreduction of deforming regime are analyzed.
