Abstract
In three-phase electrical circuits (distribution electrical networks for alimentation with electrical energy), the non-symmetric situation may be characterized by the existence of negative and zero symmetric order components of the current, which have a bad influence on the efficiency of energy. One of the explanation is the instantaneous power flow of negative and zero components, as it is analyzed and explained in this paper. On symmetric situation, only the positive sequence component exists. Finally some simulation results are presented and also the experimental values, which were measured with ACE2000 device in electrical station for trams supplying trams with electrical energy.
