← TechnologyWhich outcome occurs when reactive power demand far outweighs a power grid's surge impedance loading?
A)Voltage sag on transmission lines✓
B)Ferranti effect raises source voltage
C)Reduced transformer core saturation
D)Improved system power factor occur
💡 Explanation
Undue reactive power demand causes voltage collapse via voltage instability, because the grid undergoes high current flow, therefore creating larger voltage drops along the transmission lines, rather than voltage increase, which is the Ferranti effect at light loading.
