← TechnologyWhich outcome occurs when a generator connected to the grid experiences sudden, uncontrolled, increase in reactive power output?
A)Voltage sag on the distribution grid✓
B)Transformer oil overheating consistently increases
C)Automatic increase load on generator
D)Improved power factor near unity
💡 Explanation
If a generator suddenly increases reactive power, voltage sag occurs because increased reactive current (Reactive Power Compensation) causes a voltage drop across inductive reactances. Therefore voltage decreases, rather than power factor improvement, which requires management and stability control.
