Two voltage phasors of a three-phase unbalanced supply are measured as Va = 21820°, Vb = 2402-110. There is no zero sequence components in the three-phase supply. (a) Determine the voltage unbalance factor (VUF) using the IEEE definition. (b) Determine the ß and then calculate the VUF using the IEC method-1. (c) Calculate V-, V+ and then calculate the VUF using the IEC method-2 and compare with the IEC method-1.
