The initial three-phase voltage phasors $\left(\bar{V}_{A}, \bar{V}_{B}\right.$, and $\left.\bar{V}_{C}\right)$ 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?
- The zero sequence components in Case-$1$ and Case-$2$ have the same phase angle and magnitude
- The magnitude of the zero sequence component in Case-$1$ is greater than that in Case-$2$
- The magnitude of the zero sequence component in Case-$2$ is greater than that in Case-$1$
- The zero sequence components in Case-$1$ and Case-$2$ have the same magnitude but different phase angles
