← TechnologyWhich outcome occurs when ground fault occurs on distribution transformer secondary circuit?
A)Overcurrent protection tripping instantaneously✓
B)Voltage imbalance causing motor overheating
C)Transformer core saturation from DC current
D)Resonance generating harmonic amplification
💡 Explanation
When a ground fault occurs, a high fault current flows through the grounding path activating the overcurrent protection device, such as a circuit breaker, instantaneously due to exceeding its trip threshold.. Therefore overcurrent protection tripping results, rather than imbalance, core saturation, or resonance which require different conditions.
