← TechnologyWhich action occurs when differential current protection detects imbalance within a power transformer?
A)Bypass regulator activation initiates cooling
B)High-speed breaker trips transformer circuit✓
C)Automatic tap changer adjusts voltage
D)Capacitor bank switching improves factor
💡 Explanation
When differential current protection detects imbalance, a fault is indicated because current entering the transformer should equal current leaving. This triggers a high-speed breaker to isolate the transformer, preventing further damage. Therefore, breaker tripping results, rather than cooling, voltage adjustment, or compensation which are stability responses.
