Abstract

This work aims at resolving the issue of a model that uses symmetrical mathematical components, dedicated to longitudinal simple unbalance for three phase radial transmission electrical lines of an electricity distribution system. The symmetrical component of both current and voltage are obtained, as well as values of the electric distribution system parameters, in order to determine imbalance factors which may characterize quality of supply service for the electricity end-users.
