A perspective on current unbalance in low voltage distribution networks

This paper presents a mathematical model used to calculate the symmetrical components of the load current in electrical distribution networks of low voltage. Based on the mathematical model proposed power lines were calculated tasks under sinusoidal. Case studies dealt with non-symmetric mode due to load imbalance on the distribution network of low voltage. Analysis of case studies was done by modifying the actual values of the phase currents and differences related. Important assumption is that the distribution network is symmetrical phase voltages.
