← ScienceWhich consequence results when reactive power oscillations overload transmission lines?
A)Voltage collapse spreads quickly✓
B)Improved power factor correction
C)Increased transformer core saturation
D)Harmonic distortion decreases overall
💡 Explanation
Voltage collapse spreads because of excessive reactive power demand causing substantial voltage drops; this happens through a process known as cascade tripping. Therefore, voltage collapse occurs rather than improved power transfer or lower distortion, these involve opposing conditions.
