← TechnologyWhich safety outcome relies on differential current protection in three-phase power transformers within distribution networks?
A)Reduced inrush current magnitude
B)Limited core saturation effects
C)Faster fault isolation duration✓
D)Enhanced voltage regulation accuracy
💡 Explanation
Differential current protection detects internal faults by comparing currents; specifically, a significant difference triggers circuit breakers, isolating the faulty transformer rapidly because imbalances reveal winding failures, therefore limiting damage rather than addressing inrush, saturation, or regulation.
