Abstract - This paper presents a generalized approach for three-phase networks with ground return, from which single-phase networks with ground return and conventional three-phase networks are obtained. The resulting model allows a more accuracte analyses based on ground resistivity, losses and high-impedance faults location. The modeling starts based on the single-phase network with ground return leading to the three-phase one.The general three-phase network with ground return model is presented and seen as three different geografic routes single-phase networks with ground return. Analysis and discussions about the model are presented mainly over ground resisistivity, feeders lenght, and distribution systems aplication as well.
Distribution networks, faults of high impedance, return by earth, modeling phase single, resistivity.
