← TechnologyWhich outcome occurs when reactive power surges in a three-phase power transformer circuit beyond its compensation capabilities?
A)Voltage collapse at load points✓
B)Increased core saturation
C)Decreased temperature differential
D)Harmonic current cancellation
💡 Explanation
Voltage collapse occurs because excessive reactive power draw overwhelms voltage support infrastructure using Static VAR Compensators and similar devices, therefore the overall system voltage suffers locally from increased line impedance, rather than core saturation effects or improved thermal stability under these transient conditions.
