Efecto del desbalance en las cargas sobre la valoración de confiabilidad de un sistema de distribución de energía eléctrica.

Many three-phase distribution feeders are unbalanced because, first, they serve their customers by means of single-phase distribution transformers; second, they use components which operate in single-phase manner; third, most of the failures that affect their components are single-phase. This important fact must be included in reliability studies because, as shown in this paper, when the contrary is assumed pessimistic assessments of the reliability indices are obtained which could lead to erroneous investment decisions.
