The initial three-phase voltage phasors (\(\bar V_A\), \(\bar V_B\), and \(\bar V_C\)) at a bus of a power network are as shown in Case-1. Due to a disturbance, the bus voltage phasors changed in phase by a small angle \(\Delta\theta\), and the magnitudes remained the same as depicted in Case-2.
Which one of the following statements is correct about the zero sequence components?
