← TechnologyWhich outcome occurs when excessive harmonics corrupt the zero-crossing signal used by a three-phase transformer's breaker?
A)Spurious breaker trips more frequently✓
B)Transformer core saturation decreases linearly
C)Feeder voltage regulation improves rapidly
D)Inrush current magnitude diminishes sharply
💡 Explanation
Excessive harmonics distort the zero-crossing detection, preventing accurate fault identification; this causes spurious breaker trips, because the synchronization deteriorates, therefore generating false positives rather than correctly discriminating faults.
