Unbalanced 3 Phase Loads

Unbalanced 3 Phase Loads

An important property of a three-phase balanced system is that the phasor sum of the three line or phase voltages

3 Phase Balanced Loads

Power in Balanced 3 Phase Loads

Balanced loads, in a 3φ system, have identical impedance in each secondary winding (Figure 12). The impedance of each winding
