The initial three-phase voltage phasors (V̄A, V̄B, and V̄C) 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 Δθ, and the magnitudes remained the same as depicted in Case-2.
Which one of the following statements is correct about the zero sequence components?
A
The zero sequence components in Case-1 and Case-2 have the same phase angle and magnitude
B
The magnitude of the zero sequence component in Case-1 is greater than that in Case-2
C
The magnitude of the zero sequence component in Case-2 is greater than that in Case-1
D
The zero sequence components in Case-1 and Case-2 have the same magnitude but different phase angles

Correct : d
