← TechnologyWhich consequence occurs if a three-phase power transformer feeding a critical hospital wing experiences neutral current overload?
A)Main breaker nuisance tripping✓
B)Transformer core magnetic saturation
C)Increased harmonic current filtering
D)Improved voltage regulation stability
💡 Explanation
Nuisance tripping occurs because excessive neutral current creates magnetic fields that interfere with breaker operation leading to premature trips. Therefore, appropriate overcurrent protection trips unintentionally rather than the intended overload scenario for safety under specified thresholds.
